I sat in a bunch of them at Cabelas before buying mine. I have five layouts right now, but honestly, everyone has different qualities. I bought a pair of FA express layouts for $100 a piece. Frame is only for backrest, but some guys make a pvc frame to put inside for comfort. I'm usually only in them for an hour or two at the most, so I can get away with a cheaper blind. Advantage to them is they sit lower than all the rest, and are really light and easy to pack and carry. If space is lacking, they work very well. Here is a frame idea to build if you want to make it more like the full frame layouts.
