Really? Is that all you use on yours? You should try a KFL+, it will rock on your ProVari with a micro-coil. Granted on my regulated devices I aim for about 1.4Ω or above (anything lower is for a mechanical), but the vapor and flavor are quite nice.
To the OP: If price is an issue, the MVP gets very good reviews. Many people who have ProVarii also have an MVP. It doesn't have a ≈33.3hz "rattlesnake" chip, so the vape is much smoother. The main downsides are what to do if it needs to be repaired and once it's dead, it's dead. I've never quite understood the rationale of You can buy 5 of X for the cost of 1 Z. What does that matter unless one is anticipating X will need to be replaced.
Anyway, please don't interpret my comments to mean everyone should get a ProVari. We are very lucky at this point in vaping, since we have so many choices of gear. What makes me happy might bore the stuffing out of someone else. I always suggest people think about what they want from vaping right now. If you buy something a bit more advanced than you feel comfortable with, thinking that as you get more experienced you'll grow into it, by the time you do there will be a new toy on the market. I further recommend that when the person has narrowed it down to a few devices, they browse the sub-forums to see what current owners have to say.
