Looking to save $$?
Take some time, watch the used forum, build your own hood.
I managed to get a nice deal on 2 individual IC 250w ballasts/etc ... which combined with a good reflector, some time with power tools - got me an economical canopy/lighting setup that was just exactly what I wanted.
For what I was interested in spending, I couldn't find a pre-made hood in 36" that was what I wanted. If I went cheap, it was crummy bulbs + reflector, and while I could have gone super expensive - didn't see the point.
Just my take, but IMO, if cost is an issue ... DIY.
