Depending on where you live.. a few have purchased from Tek2000.com w/ mixed results. They're a Canadian dealer priced in US currency and US shipping fees which turns off most Canadians (ie 40% exchange rate)
Ebay might be an option along w/ your local classifieds.
PS- There is a used dish thread in the Cband section
fixed or with a motor? you can pull in C-Band with my egg its q 4 foot, back then it was doing what a 10 foot dish could do, but not sure how good or bad it would be with 2 degree spacing never fired it up, because it was missing a part, then I found that part years later from another dealer but I lost a reason to play with it, I use it to cover my fig fig tree with, have a fixed mount for it the feed goes in the BACK OF THE DISH, YES IT DOES....
