I was reading a blog about a set collector, who picked up a auto from a private signing done by chris potter sports. So I looked at his Jan '11 upcoming signings, there are some easy names that sign TTM for free for $12-$30 for flats. But there is one absolutely impossible TTMer for any price, I know from experience, tried sending Rocky Colivito $50 and it still came back unsigned. He signing for $55, anyone who needs to complete a set with him, this maybe your best chance. I have never done any business with this company, but they do have roughly 40 players signing in Jan, mostly mets and yanks, with some others scattered, check out the lists, you guys may need some.
