I'm not associated with the store (other than regular cust.) so don't want to commit them to anything - but it was cheaper than I could find on-line in Australia.
Perhaps ring up (or even better call in), ask for Aaron and tell him I referred you. Get the price then shop around.
Dura-Ace 7800 was what I bought. Although not all shops have them on display pretty much any bike shop can get them in from the rep. I've got the V2 unit and so far so good.
