Hmm, I can't find them now - someone on here maybe towards the end of last year had a couple of cheap project frames - one was apparently a C16-R - real cheap - ripe for a bit of fun, a powder-coating and building.  I almost bought one to practice my home paint-jobs on.  £15 sort of money.  Perhaps someone will have a better memory.  Or just hold out for a decent one ready to go.
