HTGS is anything but overpriced. If you are finding things much cheaper just keep in mind the old saying that you get what you pay for. You said; "HTGSupply seems to be way over priced when compared to a random Google Search on 400 watt HPS lights." Well not all lights, 400-watts or not, are not like man, they are not all created equal so lower price does not always equate to a better deal ..... it only means cheaper and if so then there is always going to be some reason it is cheaper that goes beyond the seller being a munificent person who hardly make anything on what they sell just so you, the purchaser, can receive a better value. That sort of thing just doesn't happen once you stop snoring and farting and have woken up.
