recommendation for new blind
I bought a Gander Mountain Invisibull 2man blind and like it. Silent window slides and large D-shaped door and cost on sale was around $120. The camo pattern and water resistance are great as well! My brother has the 3man and its HUGE! Some of those blinds you are only paying the Lakosky and Drury's salaries...just my two cents.
Of those four, I can honestly say the Primos Double Bull Deluxe is head and shoulders above the others. You can get it now on eBay for $249.99, I would highly recommend it. I could go into great detail about why the Double Bull is in a league of its own but will spare us all the time. If you have any specific questions regarding the aforementioned blinds I'd be happy to help.
