Since MAME is what it is, I have no use for my original cabinets anymore.  I have the following for sale... CHEAP.
Airwolf - Works perfect.  Monitor was replaced with one from a cherry cabinet and has burn in but once it's on, you don't see it.  The cabinet was a convert.  Comes with manual.  I paid a good dollar for this but it sits in my bedroom collecting dust.  The pic of the Airwolf cabinet on KLOV 
http://www.klov.com/A/Airwolf.html is my cabinet.  I submitted it a couple years ago.  The pic of the Marquee on that page is NOT mine.  Mine is clean.
Choplifter - Also a convert.  If I were making another MAME cabinet, this is the cabinet I would use.  The cabinet was originally a LaserDisc game so it's sturdy as hell and roomy.  The game works *MOST* of the time.  It locks up occasionally.  This is collecting dust in my garage.  

2 TRONS - I had one Tron and it quit working so I picked up another Tron for parts.  Never had the time to put them together.  No guarentee that when you put them together they will work but I guarentee it will look VERY good.  The game as it is turns on but the screen stays scrambled.  I have several technical manuals for Bally and Tron.
I know I mentioned CHEAP.  How cheap?  Well, make an offer you think is fair and it's yours.  How's that?  I live in IL and can work with you on delivery.  
Email me for more info.  I can send digital pics of everything if you like.
