Chainreaction are clearing out their Pro-lite kit since their trade side (hotlines) are no longer the pro-lite distributors. They have some Bracciano wheels down to £218 but just for today.
For the money I can't think of a wheel that comes close.

They are Mavic Ksyrium SL weight, more aero and a quarter the price. We have used 2 sets for 4 years and only ever broke 2 spokes when I was heavier...and Pro-lite sent me replacements by Airmail so can't fault that!
As for a new supplier in the UK, there is one but not made public yet so no fear of never getting parts!
