I have two favorite Bally's
Bon Voyage EM- The backglass artwork is one of the funniest you will see (Insert Coin beltbuckle, people and luggage falling out of the plane etc)
Star Trek 78' - My brother and I picked up an unrestored Bally Star Trek 78 that we shopped out and gave to my Mom for Christmas. We had my kids convince her to take them on a donut run. While they were gone we brought in the machine and set it up as surprise for when she returned. This CONTEST is perfect because my family all chipped in for the machine but spent a lot of our budget on replacing acid damaged boards, LED's etc. The displays work but can be flaky. A new set of displays would be the PERFECT birthday gift for my Mom (Oct bday).
