Shimano 600 - any era but already have the tricolor rear mech so would like to have some consistency. These are the sort of prices I'm aiming to pay, I've pitched lower, I don't think they're that unreasonable though judging by recent ebay sales.
Band on/Clamp on Front mech £12
Crankset 175mm (square taper with 2 rings) £20
Downtube shifters (for braze ons). £12 (or trade for a set of band on 600 shifters I have)
27.2 mm aero Seatpost £15
Generic headset (silver) £5
