http://www.brakequip.com/shop/high-speed-flaring-tool-kit-standard-sae-bq351I went with this one. Higher priced and yes, not used often, but I did it anyway because its for not just brakes, but fuel, vac lines, everything. Works with stainless (hard) and softer metals too.
I just got sick and tired of that dumass little flaring tool that we all have slipping and then wondering if the slippage is why I have leaks. You can do it for your friends too. Great stuff.
