+1 on Rhino. I've got two of them. Solid. I've also got an older Primos Double Bull. I think that's still my favorite. But the new ones are not the same I hear.
That said, I can't wait until I get my place figured out enough that I don't have to hunt portable blinds anymore. They are cold, drafty, and all that... I'd really rather have a few permanent setups. Taking down the portable blinds at the end of the year when they are packed with snow and ice is also a bummer.
