Are you handy? or even better have any electrical experience? You can easily buy a 400 watt kit and make your own but a very basic electrical knowledge would help. You just need to build a housing for the kit to be safe, ground everything to the box to prevent any potential fire hazards. If that makes no sense to you then I probably wouldnt do it, but it is not anywhere near as dangerous as people think. I would look into it if thats your budget and you feel comfortable with that sort of thing
