A Metal halide ballast is a metal halide ballast. A bulb, is not necessarily a bulb though. So yeah ... don't buy the plant bulbs, but the ballasts are fair game (assuming they have a good deal on it).
Ross hit the nail on the head as for descriptions of both QuickGrow and BumperCrop. QuickGrow, good selection, good prices, but you better like the smell of tobacco smoke. Stupid smokers. (Sorry to all you smokers out there who I just offended. Um ... actually, no, not sorry. Stop smoking you dumb person!) Bumper Crop ... far more upscale. Have all the parts you need and then some (e.g., replacement Mag drive impellers IN STOCK!!), prices are not bad (I paid $50 for one of my 250W MH ballasts there).
