I used kegconnection.com for my set up minus the kegs, which were on sale at my lhbs at the time. One thing worth looking into that I discovered after the fact is the local welding supply Co. I spent about $60 on a 5 lb Co2 tank new (from kegconnection) and when I went to get it filled I noticed they have a bunch of used tanks sitting around so out of curiosity asked what they would charge for a 10 lb tank when I want to upgrade...$60 filled was the answer, that was a face palm moment but oh well. If you're on Facebook there's a page called homebrew finds that posts a bunch of great homebrew deals from several vendors, that's worth taking a look at too. As far as fridges, like others said, craigslist can be your best friend. Oh, and if you're not in a big hurry, consider black Friday sales, I seem to remember quite a few great deals last year, might be worth the wait...
