I can do a cocktail Mame in a used school desk type cocktail with 13" display, new 4-way sticks, i-pac or keywhiz encoder, used computer, all ready to go for $650. That is the price picked up. Add $60 for crating and then whatever forward air would charge to ship (should be under $100 for most destinations).
The cocktail I have "in stock" is labeled "Magical Spot", and it has nice instruction cards underneath the glass, nice overlays, the bottom cabinet art is really nice on the player one side and a bit beat up on the player 2 side. The control panel currently has 2-ways and one button, but I would swap the 2-ways for 4-ways so it could correctly play Pac-Man. I believe this cocktail would properly support about 80 games, including all the Pacs, and other favorites such as Space Invaders, Dig Dug, Mr. Do, and Galaga. Of course I would only install the games it could properly play (only vertical monitor, 4-way joystick, zero or one button games that support cocktail mode would be installed).
That price should be pretty solid, the only thing that would possibly increase it was if I had to buy a special small computer due to space issues. I don't THINK I will have to do this and could check on this before we went any further.
