I fixed all my consoles by giving em' a good smack. I've got the touch, cause it works. My Sega still works to this day.
Anyways if your good with words you could probably talk your way into getting the repairs.
A tool is a tool regardless. I mean if you suck, you suck, and not even the most perfect tool could save you. And if your damn good then even with the worst tool ever conceived you could chug out some high quality shit.
