If you are good with electrical (pretty simple stuff) you can find magnetic ballasts at most electrical supply companys in almost and town. They need to have a power cord connected, mounted in a vented enclosure, and the MH socket wired but $60 for a 250W ballast isnt too bad I dont think. Thats what I went with and had no problems getting it wired up and running and im dumb as a rock!
