Problem here is what are you getting for your hourly rate. A capable tech can be worth 10 times the money as opposed to a novice. I feel if you are putting your shingle out to repair a game you better be able to fix it. None of this it needs a board. Fix the darn thing. Just venting a little, On our local pinball community we have a half dozen guys running around charging enough to get beer. I guess that is great for some but none of these guys have liability insurance, business licence or charge or remit tax. After they have messed around with the game and have given up, the machine makes it way over to our shop.
