This may sound crazy but it is the combo cabinets (dedicated) that really catch my eye. I had 10 classics in the basement and sold them all to one guy. I then purchased ms.pac/galaga, centipede/millipede/missile command, dk/dk jr/mario bros to replace them. I took an original ms.pac and turned it into a 60-in-1. I thought I was done but I saw two others that would complete the basement. One was defender/defender II(stargate) and space invaders/qix. I am not a fan of qix, if they made the combo cabinet space invaders/space invaders deluxe I would go after one more aggressively. Thanks for the response, the 3d space invaders is pretty cool. Kevin.
