Thanks for the info and encouragement!
One of the first days I was looking I saw a 64cm(if I recall correctly) Le Tour III for $100 and the pics showed it was in great condition... emailed them and told them I'd like to look at it 'tomorrow'. * poof * Bike was gone. Taking stock in what I've read on this board and in this thread that you should tell them you'll buy it.

After reading a few hundred bike ads on the various CL pages, I have an idea of what I'd buy once seeing it now. Not very knowledgeable about frames but know I want an older lugged frame on the lighter side... also have a keyword search for bikeforums.com setup for quick sanity checks.
Need to find an ad like this
P.S. - I'm envious of how many frames are out there for folks shorter than 6'! (6'5" here)
