Heya mate, firstly welcome to the best source for arcade/jukebox info on the net!
Probably not to your liking, but you can pick up cheap "radiograms" and "stereograms" of EBay that dont take much to mod (gut them and insert). I picked one up for $5, unfortunately not all the components would fit so I built one from scratch, modeling it on the radiogram (will be posting picks tomorrow as is pretty much complete)
Good luck!
