I need cheap hoods, and blowers, DIY ideas good too

Hey, I moved out here from Cali, and all my grow equipment is gone, so now I need to find or build reflector hoods for 250w hps bulbs, and I also need to find cheap blowers, any one know where to look? I think I could build a hood, but not sure shape or material to use, any tips would be great!

Oh, and FYI, some people are selling 250w hps and 400w mh on craigslist in the denver area for almost nothing! 3 for $100 and they have truck loads!!!

Thanks all,
Grow big!
