I spent two years hunting with an Ascent H12 from Bass Pro before I got a dog and would recommend it highly with some provisos. I bought mine for $600 used and they can go significantly cheaper than that. (Matter of fact, mine's probably for sale. Which isn't why I'm recommending it.) They're super stable and have a ton of room for gear and decoys. I routinely brought out 24 decoys in mine. They're also bullet proof: the hulls are tough. As for a blind, I put the Yak blind on it, and it worked well, though without the flaps, which just got in the way when chasing cripples. It was a nice boat to just slip into some reeds and hunt out of. It was also surprisingly comfortable. I'm a big guy, 6'3" and it worked well for my frame.
The downsides are the boats weigh a ton, somewhere around 80lbs, so heaving it onto my car, solo, after every hunt got really tired. (There are good loading devices that can make that far easier, but I never got one.) They're also not fast boats: they're slugs, basically. That's the trade-off for the stability and capacity, I guess. It's not so bad that you couldn't paddle out to blinds 21/27 in 30 to 40 mins or so, but you'd definitely be sweating by the end. I did that all the time. (In the boat I've got now, a carbon fiber pack boat, I come in for lunch without thinking twice. It's a very different, but waaaay more expensive proposition.)
Also, they're definitely cheap boats, so the seat, for instance, takes some annual maintenance to ward off rust, etc. But for a cheap and versatile way to get out there, it was excellent. Good luck with your search. Kayak waterfowling, especially in early to mid-season, is highly underrated.
