eBay and Craigslist finds

Hi Folks, I'm currently trying to find a road bike to convert to fixed gear for summer fun and possible commuting. Only ridden mtb for ages so no clue about road/track or fixed gear bikes, but tried my friends fixed and loved it. Anyway, been looking for parts and donor bike, haven't found the bike yet though and I found this tonight, would it be good to use to convert a road bike, decent value at this point? I found another thread on here about them with suggests not much cheaper, but no real decision on whether they are any good. Sorry to go on, but if anyone has any tips on frames and wheels it would be hugely appreciated, thanks.

Thanks, sorry if this should of been posted elsewhere.

Figure it out for yourself. so much info on the forums and elsewere. if you cant manage that I dont think you should be building a bike.
