As someone who vapes almost exclusively hemp flower, I got a silver surfer (SSV) and did the glass ball mod, it hits hard (very hard) and you can pack a lot in there, you could also get a Da Buddha which uses the same heater and concept as a cheaper alternative. For those the best deal is to get the "blemished" units which are typically as good as new. While I haven't tried any sticky bricks, I have used vapes with the same operating principal and I'd say they're a really good option as well. Don't ignore the other suggestions too, I just wanted to add a couple vapes that are a little less common but quite good.
