I'm looking to buy a prefab sauna box. And I'm mainly interested in the zero EMF models. I'm not the type that buys into a lot of the fear mongering but this seems to be a big deal in the sauna industry. So since they are available why not go with zero EMF. Especially since they aren't all that much more.

The bigger problem for me is that there is no way to kick the tires on these things. I can't find a single brick & mortar store that sells these. It's online only, so you're making a pretty big purchase sight unseen and untested. Fortunately, there are a lot of reviews on Amazon so that is a good source of information. Does anyone have any really good or bad experiences with manufacturers that you can share? Or does anyone have some buying tips to share?

At the moment I am leaning towards this unit from JNH Lifestule http://www.amazon.com/gp/product/B00U8HJ28Q
