Got an email the other day for these cabinet/controllers. On these you will need to add your own monitor and raspberry pi or computer. But I think it's a nice solution for those that don't have room for a full-size cabinet or the budget.

Bonuses: They're set up for 2P SIM, they have all the buttons you need for most fighters, and they are likely a solid build (I have their full-size upright that holds a 32" screen).
These would be the route, IMO, if you wanted something closer to a full-blown MAME setup and not that JAMMA junk. Although they sell this kit for JAMMA, too, if that's your thing.
