Those prices seem very high. I just saw a nice looking 210 Sironar in the classifieds for $160. That's the kind of low end prices that are out there. But they usually go fast. Ebay can be a crap shoot but I've gotten some nice things for fair prices. Try putting a WTB ad up here on APUG. On the subjective side I'd look for a 90 and 210 to start with. They are common and therefore cheaper.
Also Caltar branded lenses are a good value. You will have to study to find out exactly what you are buying as far as original manufacturer but that info should be out on the web. Also always make sure the lens comes with a mounting ring or flange. You don't want to get stuck having to buy the mounting parts separately and some flanges are expensive.
