The stuff on e-bay is basically all made by the same seller who goes under different names depending on what level case you're looking at.
I went through an agonizing process trying to figure it all out, and after calling all the numbers of all the sellers, I realized I was talking to the same guy. Like you, I'm not planning any world tours, so I didn't need a case that was true ATA spec. FWIW, if you are looking for that, you're going to spend a minimum of $400 to get something decent. And as manetioned, they weigh a ton.
The e-bay cases actually aren't all that bad, and will do what you want, but you have to make sure you spec it out with everything you want/need. For example, some of the "basic" cases look good, but only have carpet inside, which isn't really going to help much or offer any real level of protection. I got mine with foam inside, recessed latches, wheels on the bottom, and non-recessed handles, and I think it came in at around $160. It's worked well for what I use it for (protecting against accidental dings during load in/out. It's protecting my bubinga and wicker F-50.
I think I have other posts out there on the same topic where I get into greater detail.
