www.heavenlyheatsaunas.com These saunas are completely non-toxic. You said you can only spend about
$1500. but be careful of the materials that they are made from. Heavenly heat are Tall glass saunas with white poplar seats, no toxins whatsever. They are also vented, VERY important to get rid of toxins. They have stone and IR heat units. I used one daily for a year, great detox and miss it alot. I hope to buy one when I find a new place to live. If you cannot afford new, I have seen them on craigs list. Good luck, you will love it. D
