I could take a couple pictures of mine with a list of parts I used and where to get them for you. Another freind is currently building one right now and a Doctor freind is also building one for his new house. His wife has MCS too. I haven't been able to use mine much yet because I'm too sick still but its there now when I can.
I know several people who have had "miracles" with theirs.
One friend used his fairly heavily for a month and had a symptom reduction of 90 to 95%. He went from being mostly bed riddenn for several yeard with Fibro and Mcs to now living an active and very close to normal life. Others have abated cancers and so on. Europeans have used this technology for a whil and are also getting great results.
It is also important to not that the main detox centre/hospital in America uses far infra red sauna thereapy as one of their most important legs in their treatment protocol.
I'll track down some websites that can give you more info and then you can make a more knowledgable decision. If and when your ready, just let me know.
