I've hunted in several different production models, and some homemade stands.
Of the production models, these are my observations.
Atascosa, with stairs. The stairs are nice, and they are tight and rodent proof. Problems for me have to do with the windows freezing shut, so that they won't slide and half of the floors were very noisy. These were all purchased new and less than one year old.
The Blynd - Just a cheap economy model that can be made into a 4x8. The access door is a PITA when setup as a ground blind.
BOSS Game Systems - Probably my favorite overall. Tight windows and doors, the windows flip up, and have felt to keep from being noisy, and the floor does not creak under a shifting load.
