LF: Electronic 150w Metal Halide Ballast.

[mic209]

So I just picked up a 3 month old Hamilton 150w Cayman Sun, the magnetic ballast is a little too big for my situation and I'd have to leave it outside the stand and I don't think that will be wife approved. I really don't want to dish out $150 for a new one at the moment, so I would like to buy or trade for a good brand used electronic ballast. Let me know what you have.
