I appreciate this may be too crap for what you're after, but I've got an old (bout 15 yrs) Peugot racer if you're interested. Bought it from Butterworths opposite the Broadfield and the guy had fitted new gear and brake cables and new brake blocks. Its old and it doesn't look flash, but it goes.
I paid him 40 for it, but would obviously sell it for less than that
