Wanted: Shimano Double Groupset or Part Groupset inc STI's - Cheap

Am after a cheapish used Shimano road groupset , 8, 9 or 10 speed.
Cranks 170mm length or less, double - compact or standard.
STI's not downtube shifters

Cosmetics not important as long as good working order

I've got a bit of a mish-mash of components.
105 '9 speed' era left/double STI & 8 speed Sora both in excellent working order & cosmetically good.
Shimano 600/Ultegra tricolour front & 500 rear dual pivot calipers both in good nick/good pads.
Shimano 600/Ultegra tricolour short cage rear in good order
Shimano 12-23 8 speed cassette with an average amount of wear but not knackered
Or a new unbranded 12-28 (extra £9)
I've got a useable YBN chain that came off my commuter when I swapped from 9 to 10 speed or I might have an HG chain somewhere.
I've an older shimano double front 28.6mm band on (TY series) which works great & is good cosmetically, is fine with STI's.
£79 posted, £88 posted with the new cassette

I don't have much crank wise I'm afraid except a 170mm lightweight Red S (stronglight fluted copy) 86mm drive side crank (so you can run any ring combo from 28 to 52) however the left side crank has remnants of a crank cap in the extraction threads. you can tighten it down but it's a pain to get off. Add £10 if you want them

Bump - still after complete gruppo, black ideally 170mm cranks or shorter
