Steve, the Ribble framesets that TSL mentioned, are a bargain, as are those offered by Nashbar, both from their respective websites. Also, if you haven't looked on eBay in either current generation or their Vintage Cycling for framesets. EBay has pretty much every material to choose from as well as a nice selection of steel Vintage from next to nothing to classic Italian, English and French frames.

Like TSL mentioned though, if you don't mind aluminum, (I ride it every day) the house labels for the big websites/dealers are a good value. Both Ribble and Nashbar have sales on a rolling basis for their in-house brand frames in aluminum and CF in some cases.With all the different frames mentioned here you could be busy just shopping for a while, don't lose valuable riding time banging your head against the wall, save the serious looking for late, sleepless nights or rainy days. Best of luck on choosing your build.
