It's not just TBirds. Do an eBay search for Warwick and then sort from high to low cost. Last time I did that 97 of the first 100 listings were out of Japan. And if you look close you'll find many of those listings are selling the exact same serial number bass, as many as 5 listings from different sellers at different prices for the same bass. In other words, there's a bunch of Japanese brokers out there mucking up ebay with a lot of spam postings.
One would think ebay would have their act together and require anyone listing an instrument to actually have that instrument in their possession, but not money grubbing ebay. Apparently, anyone can list anything they want, even if they don't own it or have it in their possession. I suppose I could go down to Guitar Center, snap a few photos of their used gear then list it on eBay for a BIN at 20% more. If I find a buyer stupid enough to bite I get to pocket the profit at zero financial risk to me. As long as I put a note on the listing that says the bass is listed for sale locally and I reserve the right to cancel the ebay auction at any time, I'm safe.
I stopped shopping ebay last year because of this garbage.
