Quoted from Brijam:
You won't be sorry. Customers love them. I have had very good luck with Comet LEDs. No matter who you buy LEDs from, buy the SMD type. Non SMD LEDs fade quickly on route, and I've had very high failure rates with them.
Sorry to hear about your power supply issues.
In my (limited) experience routing older games dating back to the late 70s, every 'new' old game you bring on route has a break-in period. By that I mean things will break for a while once you put it on route again. Once you fix the things that were gonna break, the machine tends to stabilize for a long period of time. Then most of your cost are parts that are designed to fail: balls, rubbers and coil stops/sleeves, etc.
I agree with all of this. LEDs for sure, they are easier on the games, if nothing else bulbs put out a lot of heat. Every time you put a game out you need to expect things will go wrong with it until it settles in. Between being left on a lot and, hopefully, getting a fair amount of play things will break no matter how much prep you do.
