I just found a Dahon Mariner at a local thrift store for $75. Not bad, eh. Not being in a commuter friendly city or neighborhood I feel as if I need large shoes and a red nose.
This one is in VG shape but only has one folding pedal on the drive side. I doubt I'll go as far as adding SPD's although some folding ones would be cool.
My understanding is the Mariner is for boat holds getting back to OP.
Come see us in Alabama...
