I'm on the mobile app so I can't post a link, I apologize for that. (app please robin) If you go to eBay and search "pinball machine casters, wheels. New." There's some listed in Vienna Va. Close to me. They look nice. The ad says they lock both swivel and roll. It also says it does not raise them "much". However I'm 6'3" so that's fine. I'm on hard wood and these would be nice. Just wondering if anyone has tried them.
