Small heads-up, located these guys the other day, after stalking one of the classified's sellers (as I don't usually bother searching ebay world-wide)
Bikewagon on ebay

I've bought a set of the Rev Team's, they took a week to come through and are exactly as described (1880g's with maxle, un-used/fitted – no shock pump), and even with customs and parcel farce handling charges there still less than £300.
The 140 Rev's might not be everyone cup-a-tea but he's also selling 1.5 Lyric's & Domain's (though I haven't looked to see spec/price)
Though if you need to buy a new stem/headset, it's worth checking out how much they are first (as they aren't cheap)
