Where are you located? If anywhere near Utah, check the classifieds at KSL.com. There's been a few wall tents listed lately.
You might also want to check Davis Tent & Awning's January Special. They're offering a brand new water/mildew/fire treated 14x16x5 tent for under $600.00. Angles/frame, windows, etc. are extra, but it's still a heck of a deal from one of, if not the best makers in the country, and you know exactly what you're getting.
