You can buy them... The last one I got(used Bally) was around 400.00us ,over 20 years old (my state law for even having one), and was shipped in 3 boxes, cab, reels, hopper, this apparently gets around shipping a slot over state lines and brings it down to its only parts???.... I did buy one a few years ago that had a progressive feature, Jennifer would stay away from these though, it was a real pain to trick it to not remember its life in a casino.... Oh and if you plan to trick A mame into taking coin, you will find your pretty much on your own.
