I have a Dirt Fox and a Super Off-Road for sale in the DFW area. Both are in very good condition, but the Super Off-Road is missing side art on one side. Repro art is really easy to come by, though. Or just have that side of the machine against a wall.
The CPS2 is in a red kit cab with a 19" monitor. You can have your choice of games put in it. I know we've at least got Dark Stalkers 2 and Super Street Fighter 2.
I can supply pictures upon request or you can come down here and check them out! (I'm in McKinney, TX.)
*UDPATE* Pricing data
Dirt Fox: $150
Super Off-Road: $300
Red CPS2 kit cab: price pending
I need to solidify prices on the last machine because they are co-owned by my brother. He'll have a fit if I don't settle a price with him before I sell them. I'll talk with him today (10/30/06) about it.
