yeah you get the point. spend the money and do it right. Most shops will DO THE SAME as EBAY if you bring in a pic. Mine does so i dont have to wait for the damn thing and deal with ebayers. Electronic ballass are DEF worth the money once you get to two or more lights..especially if heat is going to be a problem. One ballast alone can raise the ambient temp of a well vented room ten degrees. Much cheaper to just get the more expensive ballast. and good luck
