I use the Ameristep Penthouse. It looks huge in the store, but not so big in the woods. I can stand in it fully, plenty of room for two people. The supposed scent control system I feel is pretty much a joke. It's easy to set up, takes a little time to take down.

I set it up in August for deer season and leave it up until sometime in February or March once the weather gives me a break. Leaving it out so long doesn't seem to cause problems with it.
