Depending on what the cabinet may lack, youll most likely need an i/o board (a few were made but the capcom is preferred because it can run on naomi power supply and rca jacks) which everything seems to be getting pricier. I would say around $200 for that and the same for a Mvc2 cart 250-350. Obtaining a cab that has a working monitor, 6 buttons pre-drilled and a sega naomi mobo will get you almost everything. I bought mine at around $250 because monitor didnt work. There are repair guys in the area that can service the monitor/chassis.
