UT Athena are pretty rare: Athena was only available with UT for 2010, Power Torque after that. :(
As with carbon mentioned above, it's the same for metal cranks: Veloce, Centaur and Athena are the same crank, so unless you are matching a groupset (and especially if you are going to take the logo off) there is no point paying the premium higher groupsets attract.
The real bargain is to be had with scuffed/heel-rubbed black Veloce: these go for peanuts and you can strip and polish them for the classic look on a budget. :)
Have you considered the Campagnolo Athena Ultra Torque chainset? it's alloy and most likely much more durable than the carbon variants. I have them and they're fine, you can even peel the Athena logo off if you want to.
