It just so happens I've got a Sevylor. I bought it at Wal-Mart for $40 mainly for fishing. It's the 'Hui' model and it says on it that's it's built by Coleman.
For $40 it's been quite good. It's a lot better than some of the cheap rafts so you see at Wal-Mart because the main perimeter is two chambers so you aren't sunk if you get a hole in one. It also has a really nice valve that makes inflation by mouth (~60 breaths or 5x a NeoAir) do-able and deflation is easy since you can leave it open to deflate itself unlike cheaper valves that you have to squeeze to deflate.
The only downsides to this boat is the weight and the durability. With the roping removed, just the raft is just under 5 lbs and the paddles (even using 1/2 of the shaft) is another 1.5 lbs. Regarding durability, I wasn't that careful with it initially because I thought it was tougher than it is. I put 3 small holes in the main perimeter chamber and two small holes in the floor. Thankfully the patch kit is pretty awesome. The glue dries super quick so you can get back on the water in 2 min and all the leaks have been slow enough that I can just top it up with a few breathes every 15 min until I get to shore to patch it. A friend has a similar raft and he got 6-7 holes in it during a 45 min, 1/2 mile bushwack when it was strapped externally to his pack.
Ultimately, it's not even close to a white water boat though, which isn't what I'm looking for. I'm mainly looking for a fishing and lake crossing vessel which this does okay, but the Flytepacker raft looks like it does that better for less than 1/2 the weight and the $240 price tag is reasonable. If I keep having a good time fishing remote lakes then I'll probably buy one of those.
