I recently bought a Bris 3.3 catamaran, and I'm very happy with it. It carries 4, has a massive deck area, and with one up, my bland old Parsun 5.8 2/s planes at half throttle. They are $1100 plus 90 freight on ebay. I also tried my Tohatsu 18 on it, and that was err, fun... At 3.35m it is perhaps a bit big as a tender, but I can fit it on my yacht's foredeck partly deflated.
I previously had a Takacat 260. The build quality was excellent, but at close to $4k, they are a bit pricey. It's also a "wet" boat.
My reasoning on a cheapy: PVC is PVC is PVC. The fabric doesn't last forever, so buying a brand name doesn't make sense. Sure, Hypalon is better, but one of those could blow your budget...
So, my vote is on the Bris 3.3.
