the expensive part of MH is the ballasts. if you are looking at normal 250 watt you can get cheaper bulbs from SA and buy ballast for about 60 to 80 bucks each. you will then have to build a box and such so add another 20 to 40 on top for wires sockets ect...
if you look at J&L a dual 250 watt PFO ballast is only 219.00. your not going to save to much doing it your self.. maybe 40 bucks and the home made one won't look as nice. if you want to go HQI then the price goes up to 309.00. I can tell you unless you are a lighting business you can't buy the ballasts for under 140 ea so for the average person this is a good deal from J&L.
