If you're talking about TNT Amusements in Southampton, PA -- yes.
I purchased an older Data East "Two Crude" Dynamo cabinet from them a few years ago, working monitor and everything, for $150. Looking back, I think I overpaid considering the shape it was in, but hey, rookie mistake. The guy in the shop that I dealt with was pretty helpful and let me walk around their warehouse for a while and answered all of my newbie questions.
The owner, Todd (the guy on their goofy public-access commercials) seems kinda pushy. They do great work restoring machines, though, and I think they have a decent trade-in policy on pinballs.
Haven't dealt with them since then, though, so take that for what it's worth.
