Hi all, I'm new to vaporizers and after hearing a guy rave about the benefits I decided to go with one. He suggested the Davinci Vaporizer, but it's a bit out of my budget. So, I'm thinking more along the lines of something like this: http://www.ebay.com/itm/SainSation-...449?pt=LH_DefaultDomain_0&hash=item2a28a5aba1 Is this any good and will it do all the Davinci can? If not what would you guys suggest? Thanks!
