Just went to Arcade World in Saint Louis today. Nice, small shop. Looked around asked a few questions. Here are a few things of note;
1. Small shop
2. Moderately priced arcade, pinball, cherry machines, etc.
3. They sell individual parts.. happ stuff.
4. they sell monitors and do repairs on them.
5. Took some time to talk to me... told them about BYOAC, they said feel free to drop in.
Anyway, I've been to a few arcade shops, this seemed like a nice walk-in shop for parts if you're in the St. Louis area.
