I have a Campagnolo Mirage compact crankset, 110bcd, 175mm, black, and I have a few 110bcd rings, a 48t surly (bombproof), a 50t TA specialities Zephyer, a 53t Tioga (unused in packet)
Let me know if its of interest, I also have a suitable (budget but hardly used) bb I would throw in. Price would depend on what parts you'd want.
The One23 rings I've used in the past and are very light weight, the surly I have the 48t version of for a real compact outer ring is very high quality and would probably last many many miles.
I've probably got some chainring bolts to chuck in too to complete the set.
