First, I would be curious how much the Ice Cream Man was asking for it.
After knowing that, what size monitor is in it? What type?
After knowing that, you can figure how much is it going to cost to repair/replace it.
Quick trip to
www.therealbobroberts.com or
http://happcontrols.com/ or
www.groovygamegear.com or
www.ultimar.com and you can find prices for joysticks, buttons, all sorts of stuff there.
Don't know how bad the water and milk shake damage is to the cabinet itself, but with some wood from your local lumberyard, you can fix that.
Head onto ebay, or
http://www.coinopexpress.com/ or
www.quarterarcade.com and other similar sites to find a price for a working Ms. Pac Man PCB.
I would say, based on your description, the cabinet is worth less (maybe even much less) than you are going to have to shell out to restore it.
You might have some luck with searching the internet for some cocktail cabinet plans.
