I used to use a Jakehouse Blind --basically just a little screen you pop up in front of yourself. (

I use a good cushion, a big tree, and full camo, and just sit down and blend in. I don't think I'd find being cooped up inside a full-size blind enjoyable.
As for decoys, I've had turkeys come into them, and I've had turkeys appear to be spooked by them (including a real nice gobbler that was coming hard until he crested a ridge and saw my decoy). Although many say any decoy will work, and it's probably true, I'm not entirely sure a low quality decoy will work as well as a good one (maybe that gobbler wouldn't have spooked if my deke was more realistic?).
