Can I get feedback as to where I can find the cheapest 250-600 watt hps used? Somewhere reputable and wont sell defective equipment? Anyone have any suggestions? Ive been all over amazon, ebay, craigslist and big name retail sellers. Im thinking id be best off finding a fellow grower looking to move up to more wattage and trying to sell their low watt hps. By chance, does anyone here fit that description?
