I've also gotten some good deals from Joesvintage auctions at
http://www.jvscauctions.com/catalog.aspx as well on bigger $ cards. He does a couple hundred items every two weeks.....usually 100 graded, 100 ungraded although he's been doing more graded lately. Anyway, I've picked up some decent stars there for at or less than they'd be on ebay for similar grades. Plus, ZERO commision on the buyer side for the auction.
John (Harliduck). I have some nice 1963's that I'm going to list as a lot. Probably 200+/- in EX to EXMT condition. Just sold a 1963 lot a while back on the B/S/T along with 1964. Just dupes from lots I've bought.
A great friend of mine is J.D. Heckathorn....he does those Pittsburgh shows and always has tons of midgrade cards in binders and stars in the case at reasonable prices. Look him up when you're in Chicago at Sun Times or Pittsburgh as well as the National. You won't meet a better guy.
