I've seen these in person... their build quality is cheap... cheap joysticks, cheap buttons, melamine coated particleboard... not really for commercial use... but it should work fine in your house.
Yeah, I didn't exactly expect any miracles... I mean as long as you can play the classics halfway properly. The experts of old school games will probably think it a sacrilege, but I don't need Sanwa sticks to play Donkey Kong (although an actual four way stick would be good). I guess I can still replace the sticks if they're crap or crap out after a while.
PBJ, only the machine itself costs 300 dollars, unfortunately the shipping would be at least another 150, which is why I asked if anyone would be interested in a group buy. I'm working on two other machines at the moment and I don't want to start another project, but I wouldn't mind having a nice little mini cocktail...
edit: sorry, it does say included EMS freight charge, which unfortunately doesn't apply to Germany.
edit: sorry you guys, I'm a moron, there's another pic that clearly shows that it has 2 buttons per player.
