straight shaft is better and thats the only design you will see when it's time to use a blade. the wound spring bent shaft design can not take the torque load/of the spining mass of a blade when the blade does hit something or any (other) attachments.
Big companies have lifetime shaft warranties.

Curved shaft models are fine for simple grooming along sidewalks and small properties. They're usually on the smallest trimmers and therefore more affordable.

Straight shaft models offer more flexibility. You have a bit more reach for working on banks, under shrubs, bushes and low trees (like pines) and for tearing through tall weeds and brush. Straight shafts are a must if you want the option of changing between trimmer heads and steel blades.

Coincidentally, we just shopped for trimmers last week. I looked information up online and we decided to get a Honda. We already knew how Honda engines run forever, so that was already a big selling point. What sold me on the Honda over most of the competition was the 4-cycle engine. It's not as peppy as a 2-cycle, but it's much more fuel efficient, lots quieter, has more torque and eliminates the hassle of preparing an oil+gas mix. We ended up selecting the HHT31SUNBA, which comes with the brush kit standard. As soon as we got it home, I edged all the sidewalks and trimmed around the trees. I put the brush blade on and wiped out an annoying bush and three saplings we'd been wanting to get rid of, then went to work on some heavy weeds that grow up around our brush pile. It did quite a bit of work, and I never had to refuel. We're very pleased with it.

Then with a 4 cycle you have to check the oil level all the time, your have a lot more maintenance, have to change the oil every so often, just like your lawn mower. There a 2 cycle trimmers on the market that are just as fuel efficient as the Honda with a lot less hassle and maintenance. Plus with the 2 cycle, you do not have to be adjusting valves all the time, see that a lot on Ryobi 2 cycle trimmers. With a 4 cycle youy do not have the quickacceloration, so it will take longer to do the same job.

The Honda 4 stroke has quite a different tourque curve thq a two stroke. With a brush blade on a two stroke it can bog down if you take too big of a cut. The 4 stroke will not bog like the 2 stroke. It takes a little getting use to.

Yeah, I'm loving it. I always dreaded having to knock down heavy weeds with our old 2-cycle. It was constant 'nibbling' to keep it running at top speed, otherwise it'd quickly crap out. Based on how the 4-cycle ate those 2" trees and breezed through the high grass I cleaned up, it ought to be easy to knock down any errant junk that grows up around the field.

It is all a matter of personal preferance. "Most" curve shaft trimmers are the cheapest thing you can buy.
You can get a good Redmax curve shaft trimmer for 149.99. These are an excellant light weight, easy starting engine. They are a 300 hour EPA rated engine. That is the top rating that can be got on 2 cycle engines. 22.5cc engine, fleax shaft trimmer. You can also get a good straight shaft trimmer for 199-269.00. The 199. trimeer has a flex drive shaft, the 269.00 has a steel drive shaft/ Both have a 300 hour EPA rated engine. That means that it is rated to run for 300 hours and still meet the EPA guidelines for pollution. Don't get me wrong, Echo is a good trimmer, but every commercial landscaper that I have got to try a Redmax trimmer and are used to Stihl and Echo want more Redmax equipemnt and they quit using Echo and Stihl. Plus with the fuel prices Redmax has a Strato-charged engine and it will use 1/2 the fuel of any other trimmer on the market. I know you are not going to buy it from me, I just want to you to get the best trimmer for the dollar, so before you spend your money, look at a Redmax.

I second the Redmax trimmers. Get one with a reciprocating head, not cheap but worth the money. You no longer will have grass, dirt, rocks etc thrown on you, cars or anything else. Can't be beat for safly edging sidewalks, around trees, flower beds etc

I've been looking at weed trimmers alot lately. The curved shaft ones are the cheaper, low end models generally, small motors, etc.

Straight shaft one have a flex shaft also, but are more robust and heavier built and have larger motors.

I've been looking at the Echo models in particular. I've had several lawn service people and one ex-lawn service maintenance man, and a couple of dealers that sell alot of stuff to the lawn service biz, tell me that the Echo is the best power to weight ratio, durability, price, etc. combination. There are better ones out there, more pricey, pricey ones that are not as good, less powerful ones that are heavier, etc..

Echo makes one model that has the straight shaft with a steel shaft in the place of the flex shaft.

Stright shaft models generally get the head further from you.

Echo also has a neat head that you don't wind string on. Instead you cut the string into short pieces about 8 inches or so and insert them in a hole with a one way finger in it to catch it. If it breaks or wears out, you pull the remainder of the string thru and insert a new piece. Just keep a few in your back pocket. I'm told it works well.
