I've got the 130-amp MIG from Eastwood. I haven't used it a lot, but so far I like it. I don't have a gas cylinder yet, so all I've done has been with flux core wire.
I looked at the 130-amp Hobart, but it only has 4 or 5 amperage settings...whereas BOTH the wire feed and amperage settings on the Eastwood are infinite, between the high and low points.
I used Miller equipment at the frame plant, and the one difference--might be the flux core, might be the welder itself, I don't know--is that there's a fraction of a second delay between the wire feed starting and the wire being "hot"...not enough to be a MAJOR problem, but enough that it's noticeable.
When connecting the terminals to their respective positions when installing the MIG gun, I found the wires to be about an inch too short. Rather than fuss and fudge around, I cut the terminals off and soldered in about 2" of wire, covered with heat shrink tubing, to make them reach. I figured that, since the wires have to be reversed to switch polarity between flux core and solid wire, I needed a little extra length anyway, so that the copper wire didn't work-harden and get brittle before its time. I figured if I called Eastwood and had to send the MIG gun back, I might end up getting one that had leads just as short, or worse.
But as far as function, I've not had a single problem from mine. I'd recommend it, based upon my hobbyist use. Now, whether it'll stand up to rigorous day-in and day-out use, I guess when we start to chop the top on my '52 International pickup this spring, we'll find out.
And spare tips and nozzles are as close as my local Harbor Freight store, or Tractor Supply.
Hope some of this information is helpful.
