No, I'm "bostonbilliards" on eBay. I have listed a couple of flawless or near-flawless sets of Centennial TV Tour Edition balls there.
I'd be closer to $500 for my set because it's likely flawless. But $400 isn't unfair. See if someone else has one here for that. If you don't hear back and are interested, let's work out the details by PM. Good luck with the search.
