Are you looking for something portable or more of a desktop unit? If you're looking for a home unit, I'd get an e-nail. Easy to clean, great flavor, and easy to use. The EVO is nice for oil, but I don't really like how you can't take more than a few dabs at one time unless you have a lot of nails, which are expensive for what they are. They're also kind of a pain to keep clean if you use them a lot. Does taste awesome though, and would be a good choice if you're also going to be using flower with it.
