Funny how we all do this with tools, buy the cheap one, have it break at the worst time, then pay up and spend weeks second guessing it. The $40 clipper always seems fine right up until it isn't, and then the good one feels like a scam until you've used it a dozen times. Give it a few haircuts and the price will stop bugging you.
Man, that's just how it goes with everything, not even tools. Buy the cheap version, it works till it doesn't, then you get the good one and feel weird about the money for a bit. Same thing happened to me with boots and a coffee maker lol.
