The place on 60th and Grover is called Greater American Distributing. They have nothing, don't waste your time going there. They are not bad if you need a game repaired, but they have nothing for sale there.
NTS is your best bet, i also got my empty cab there. He's right though, it'll set you back about 100.00. They've got alot of games for sale there too. Some are outrageously high, others are reasonable.
