Hmm
Have you any Gottlieb System3's in your collection?
They seem to go for a good price and are great fun to play...
I think Tony Turner had a Cactus Jacks? (if you need a quick hit) They are great fun and a good laugh.
Mark has some excellent titles coming in soon - BK2000, Class of 1812 etc.....
I understand the whole cash burning a hole in your pocket syndrome....I suffer from that badly too.!
