would you be interested in an 05 or were you looking for an older model?
How about a used for one Ironman (and a win I might add) Corima front- more 303ish than 404ish though.
watch out on running standard brake pads, you’ll eat through them in no time. You need to at least run Kool-stop black pads, or the Shimano or Zipp carbon pads. You can still run these pads with your regular wheels so you don’t have to switch out.
