i'll get another $80 1982 TREK 420 of CL.
How long would it take you to find that deal again? How realistic of an option is that for someone who has a need for a bike in the near future? When I bought my first old road bike off CL, it took me a month of searching to find one that fit me that wasn't a pile of crap at a good price, and even then it still needed a complete overhaul.
I could tell the OP to just go buy a $27 immaculate Le Tour from the Salvation Army like I did, but as one that shops there frequently, I am well aware that I luckily stumbled upon a deal when it was still available. It is cool when people find deals, but thinking that a deal is a realistic option for most looking for a bike is silly.
