Lifepro ZenZone Sauna Tent Outdoor Portable sauna.  Used a couple of times in the backyard.  Makes a great tent too.  Had a heat stroke so can't do the heat now. I just used small dry twigs from the yard and it really got the rocks hot.  Also like that everything breaks down into easy to carry bags.  Not a huge process for setup/takedown. ($250 obo)
