I've owned the 5, 9, 9H, Saga 12 and now the DX. This is by far the best yet. Haven't tried to add games as of yet but it is an option. Its easy to hide games you don't like. There are not a bunch of double or triple listed games like the 9H. New more powerful hardware plays the games better; and newer games are on offer here. Every time I get a Pandora cabinet up and running it gets sold, but I think I'm keeping this one for me!
Dont forget the power supply. DIY retro arcade; ya can't go wrong!
Always great service and support. Items/parts are priced fairly, shipped promptly and delivered safely!
