Here's a good price on the Veloce gruppo. $525 plus some shipping.

Veloce should work well on that frameset, although I must say I have been finding some very good deals on used 9 and 10 speed Campy gruppos as of late.

I don't know if you plan to use the bike for "spirited rides" with friends or training purposes, but the Veloce gruppo feels and performs quite nicely at that pricepoint.

Doesn't have the fine finishing of a Centaur or Athena gruppo, but it is several hundred dollars less, so you'll quickly get over that, I'm sure.

Should work for you.
