I agree 100% with checking the sale adds after hunting season is over. I have set-up a bunch of wall tents before. I have used Salem tents, Reliable tents, Montana Canvas & Rainier tents.
My favorite out of the four brands is the Montana canvas with 5' -walls. The reason why is the roof pitch is nice & steep. The steep roof pitch helps add room to your tent. You will not have to bend over as much when you walk around in it.
I recommend buying a Kwik Kamp frame for any tent you buy. Kwik Kamp frames make set-up a breeze. I can set up my 16' x 20' by myself in 20-minutes with a kwik kamp frame.
