The best way I know of to do this is setup manually, so I'll try and explain it that way.
Go to
http://www.ebay.com/sch/ebayadvsearch.
In "Enter Keywords or item number" I have the following so far. This is everything you want it to hit. Set it for "Any words, any order"
( (coin op,, coinop,, takes quarters,, pin ball,, pinball,, pinnball,, pinabil,, pinabill,, arkade,, aracade,, acade,, acrade,, arcade) )
"Exclude words from your search" is pretty self-explanatory.
This is what I have so far. I have "2600" and "vcs" to filter out some of those pinball games without flagging "atari" as a bad word, for example.

Search is "All Categories". This is a general suggestion for all eBay searching. I find limiting the category limits results, people list things in all kinds of odd categories and if you search in a specific category you will filter those results out.
For even higher hit rates, select "search in title and description". You'd be amazed at the stuff you can find with this check box, but it takes a lot more filtering out of words and you have to be careful to not filter out arcade games by the words you use.
Scroll down to location. Set it within a reasonable distance of your zip code. Basically, a little over the maximum distance you're willing to drive to pick these machines up. Keep in mind, you might be willing to drive 200+ miles for a super
machine...rare on eBay, but you never know.
Sort by "distance nearest first", so you are getting results by how close they are to you. I like to see more hits, so mine is set to 200 results per page but you can set that how you like.
NOTE: this is still very much a work in progress, let me know that search terms and filtered out words you use and what kind of success you have with eBay advanced searching. I don't think there's a limit to how many words you can search for or filter out, so this can get very refined.
