RE: ground blinds
Well, as I am sure you have noticed, just like anything having to do with bowhunting, the sky is the limit. IMO the very first thing you need to do is set your price limit and stick with it. Then what features you want. You can find a pretty decked out blind for little money, and a pretty plain Jane model for a lot of money.
Personally, I havea Trophy Den from Hunter's View. It sets up fast, lightweight, and is very roomy. Now, it was a $69 blind, so it does have a few faults, but all of which I can live with. For instance, when you net the windows, the zipper for the outer window is between the net and the window, so you have to open the outer window before getting in the blind. The "hubs" are flex tubing held together with velcro and some duct tape I installed later. It sounds cheap, and it is, but works incredibly well. I really abused this thing last spring turkey hunting and it held up perfectly.
