Hey guys. I'm looking for some recommendations for a good and inexpensive vaporizer for herb. I f'd up my back a couple months ago and have been using increasingly more medicine as the pain and tolerance has gone up. Medical bills are ramping up, so no way I can afford anything nice like a Volcano. I've seen some pretty inexpensive box-style vaporizers on eBay and Ratuken, but after a bad experience with a fake MicroG pen that I got on eBay I am very leery of ordering other vaporizer products there. Thanks in advance.
