I've been lookin at provaris for a while but can't justify the price
I said the exact same thing. Bought another mod in the $100 range (won't mention the name, as it is not my intent to bash). Started having problems the first week, fixed that..... Two months in the problems reappeared and I have thus far been unable to fix it (reads extremely low Ohms, then short, and won't fire).
Ordered a ProVari blem and now cuss myself for not doing it earlier. But, as JaxGator said, if I had not experienced the first one I might not appreciate the ProVari as much! Experience is what you get, right after you really needed it!

About as long as my spending "guilt" lasted with my first one, I purchased it used - received it, tried it for the first time and immediately went to the ProVape site and ordered a brand spankin' new one.
