I've used traditional flaring tools for 25 years now and made tons of flares, and while entertaining, I have no desire to go back there.
Generally I've always found the cheapo ones to be a PITA and have always tried to get something better but options are limited up here. I thought RIGID would be the answer (it was well over $100) but it crapped out after several flares (and never did 1/4 well) and the RIGID was not helpful in backing up their tool.
