I'd go new.

Or maybe a used 10 speed Chorus gruppo for example.

I've been able to snap up some real deals on this gruppo.

So many great choices on new Campy gruppos as well.

...and so many holiday sales going on from the likes of PBK and Ribble.

You could go with a complete silver 10 speed Veloce gruppo with Fulcrum 5's for less than $900, up to an Athena gruppo with the same wheelset for about $1,100.

As for 8 speed Campy, I have it on my Colnago Elegant and it is fantastic.

But we checked around today and all the 8 speed we saw was spendy when you add in wheelsets.

$650+ with a wheelset was the quote I have from a friend with a gruppo for sale.

Whatever you choose, I think silver would be my choice for that frameset.
