Are you after something retro or are you not really fussed? I've got some NOS Black raceface North shore for £30 they are just cranks no rings or I've got a clean shimano Chainset including rings for £25 and I've got a really nice Raceface Evolve XC chainset including bottom bracket for £60, or if you're after something retro I've got LX, DX and XT.
