I've got an IceCap 250 watt Metal Halide ballast with Spyder Light reflector and mogul socket just sitting around. It's got a used bulb in it. New this stuff would probably cost you $160 or more, but I'd be willing to let it go for $75 + shipping.
I've also got a VHO set up. It's an IceCap 660 ballast with heat sink and
wiring harness. It's currently set up for 4 x 36" VHO bulb with waterproof end caps in two separate 36" caps and reflectors. This set up would cost about $250 new, but I'll let it go for $150 + shipping
