I just picked up the Arcade Treasures Deluxe (2 and 3, 4 discs total) for 10 bucks at ebgames.
The only bad thing about this set is the annoying CD Copy protection. The CD has to be in the drive and it takes a good 30s to a minute to finally launch into the front end.
The Namco 50th anniversary collection I picked up is the same way. Except this one does it whenever you launch a game from within their menu. Very annoying, especially when trying to get them to run out of a frontEnd like I am
.
I've been picking up a lot of these collections to find the ones that can used in cabinets. I hope to have a nice write up of all I have learned in the next few weeks.
