I'm looking to start my own electronic repair services, but I'm low on funds and need to buy a heat gun for doing things like removing screens and small components (like charging ports). I'm trying to find something that is less than $30, and at most doesn't pass the $50 mark and has precision. Trust me, if I had the money, I'd buy a hot air soldering station (I think that's what it's called), but it's expensive as can be to me. Does anyone have any suggestions of something with good reviews or is from a trustworthy source?
