I am in the N. VA area as well.
I know of a potential source but I cannot tell you in good faith that it is a sure thing.
There is a home gameroom shop owned by two partners near me. One is a total dick, you want to hit him square in the chin after being in his presence for 5 seconds. The other fellow, Paul is a nice enough person to talk to and you can tell he really loves the classics. He doesn't like MAMErs though because they always want to meet him on a SAT when he has hockey and try to bargain him down to less than the agreed upon price for a cabinet. He has offered to call me a few times when he was at his storage unit but he never followed through on it.
All that aside, he is a relatively nice fellow and I think that we can work with him to do a group buy on some cabinets.
I was also looking at getting a group together for the November Auction in Baltimore, split up truck rental or something.
Let me know if anyone is game.
