Re: FIR sauna heaters

Hello,
I've been looking for FIR (Far-Infrared-Sauna) saunas for a few months and having a difficult time deciding which one to go with. I dont want the inexpensive tent style where your head sticks out the top. I'd prefer the cabin style, with a door which shuts, etc. Any suggestions from those who have recently purchased and probably just as important why you chose the one you did. The MPS sauna looks impressive but out of my price range at this time. I'll have to work on manifesting the money for that model but in the mean time, what is the next best?
I am an independent massage therapist with a small practice and am looking for an FIR (Far-Infrared-Sauna) sauna to add to my offerings; I want the best quality for my budget.
