I have a Troll and a Deringer clone. The Troll is top notch to me. I see them popping up more and more, as they are on the cheaper end of authentic RDAs out there and blow clouds for days. Dial the air back and the flavor is on point. With the four post hole design and large deck space, it should be fairly easy for someone getting into dripping to build on. I got mine from vapordna.
