I like Davis tent also. Very nice folks. But, you should also consider Montana Tent. I saw both at the RMEF meeting in Reno. Couldn't decide between the two....but, Montana tent had a better show special.
Either way I don't think you will go wrong.
You can also check out
www.govliquidation.com and see if there are any thents up for auction in your area. They usually go for hundreds less...but, most of them are used. It really helps a lot if someone can check them out for you before you bid. Most do not seem to come with frames.
