I am not having much luck with the local Craig's List for finding a tandem. In particular I'm looking for something that my 6.5 year old can ride as a stoker without adding a child kit (more $$$, complexity). he's about 4' 2". Some models like the Trek T900 or the Burley Zydeco Mixte would work perfectly. I also need an upright style to avoid as much hand pressure as I can due to some mild carpal tunnel. However, mostly what comes up on CL is old Santana or Cannondale road bike tandems - not quite what I'm looking for.
So - aside from CL, are there any other good sources for used tandems? Thanks!
