I've got a Dewalt DW744, say '07 or '08 vintage. I needed one, as I was doing contracting work at the time, and it was warranted by on job alone, no real complaints about it at all, was fine for anything I've had to do with it since. It's got enough power, obviously a sharp blade is key to that, its actually got the original still in it. Portability is good with it.
My only concern is putting a dado stack on it. I believe the blade throat can be changed, but there may be a minor issue with the arbor and or the orientation of the motor to consider, I think I read something about that while researching this sometime back.
I would say its usage matches what you are doing, some of my work was of the same type, repair, small jobs, some new work as well. I've ripped actual 2" pine with it, as well as 1" D4S or finish lumber. I have not tried other blades and any significant hardwood material, it was fine for the floating or what is it, the composite flooring, did one large room with it for a customer whose installer bailed on her.
Locally you do see a lot of various kinds of table saws on CL, older stationary, contractor/portable, and for woodworking equipment, its not a bad place to check, however as common sense, one is wise to look these things over carefully. You'll see one listed, one job or one time use, no longer needed, discounted, if it checks out, price is right, "potentially" a good buy, some list them close to new retail, and in that case I'd just go new. I'm a firm believer in buying new when it comes to these kinds of tools/equipment, because if you are going to spend a significant amount, it just makes sense, but that does not mean there are not good deals used, its wise to check them out, make sure it will cut true, no motor problems or safety issues, its complete that kind of thing, in my very humble opinion LOL !
