I'm fast becoming one.
Currently scouring ebay and gumtree daily for something with a nice 531 frame that I could potentially do up in time for the weather getting better. Slim pickings though, especially considering my limited budget (probably sub £250). Sure something will pop up eventually. Other option is to build it up as frames on their own are easy to come by but that would be pretttty expensive.
My current whip is this strange german road bike from the 70s (i guess). Its all black with DIPLOMAT written up the side of it. Can't find out any info about that model in particular, which i quite like, even if it is pretty heavy and got the cheapest sachs huret components that are all over road bikes from that era. Might get a photo of it up if I can be bothered.
