I'm yet to own/work on a Bally but I've had both Williams and D.E.
+1 on the C.V - I've played one at Marks for some time. Great to play and great artwork.
As far as good priced machines go, my LAH was a great choice. Lots of toys, great fun to play and well built.
I really enjoyed Mark's Safecracker too, but rare and out of my price range.
T2 is a great DMD game and Getaway is lots of fun too.
