I've got a 105 5800, 50/34t in Black. It's lightly used with a few marks from normal usage but still has plenty of life left in it. It's only ever been used with clipless pedals so there's no heel rub.
It only came off the bike as I picked up a more a subcompact 48/32t chainset
I'll get some piccies if your interested?
edit 172.5mm crank length
