Traded (yes, traded) at Game Crazy; it's convenient for me -- your milage may vary. People were nice, unlike the Funcoland geeks, so that helped, too.
Picked up Karaoke Revolution. FUN. As long as they start making expansion discs for say, the 70's AM Gold and 80's, I'll buy. "Bizarre Love Triangle" is my fave on the game, as well as "Ladies Night." With all things Jacko upside down, I'm sorta boycotting them unless it's picked as a random. The 60-dollar game comes with a USB-mic, so now I have two -- which is great for duets.
Also picked up Mario/Luigi Superstar Saga. So far, so good. Great graphics, and inventive game play (using A and B seperately takes some time to get used to, however)...
Ok -- so not REALLY MAME, but just a heads up on Midway's Arcade Classics disc for PS2: 12/12 is the release date. I can't wait for the goodness that is Smash TV, however.
