Hot Tent?

I am a 69 year solo old elk hunter. I need to purchase a hot tent for hunting. There are a lot of hot tents on the market. I was wondering if someone could clue me in on a good style hot tent and wood stove. I've been leaning toward a bell style tent for the standing room (5' 11"). I've been using a 3-season dome style tent with a Mr. Buddy heater, but the frost inside the tent, caused by the propane, is a real headache. Any suggestions?
