where to get osmocom-supported phones

I know this has been asked before, but I can't find the email(s). eBay in the past has generally had a few GSM900/1800 Osmocom-supported phones, although the prices weren't always great. I managed to get a V171 that way from a Hong Kong source (for about US$20 including shipping). However, the only phones that seem available today are all GSM850/1900. Someone a while back gave a link to Polish site where you could buy phones for even cheaper. Does someone have that site, or other sites that might be useful? Thanks, Scott
