Check craigslist. I bought a whole bathroom darkroom kit - everything I needed - for $80 last fall in Denver.
I just did a quick check for LA and OC and you will probably pay more than that. 20 minutes up the 405 you can get a Beseler 67C for under $100. Go ten minutes the other way and there's a guy in Orange selling everything else you need for $150.
That took me 5 minutes to find. Give yourself a couple of weeks and you can do much better than this. It took me 6 months of watching and waiting until I practically stole this one from a guy who just didn't have time to do it any more and his wife wanted it out of the basement.
