I believe that there are a number of different 50 cent coin mechs that will work in an Oak Vista/300/450 1" machine. An older Oak style with one top slot but 2 spots in the carrier requiring a small handle twist to insert the coin, a newer style with 2 obvious top slots, an Eagle (are they back/front type slots?) and one by A&A for the PO89 ? Is any one better than the others or a better value? and will "Big Oak" 50 cent mechs work on the smaller Vista type machines?
Thanks
