Hmm,
Thanks for the info but...
I don't think I would want to order anything from outside the UK TBH. I did it once and got stung TWICE - once by the delivery company for paying my customs charge (an 'Admin' charge of £20) and also by customs.
I would much prefer to order the best block available in the UK and a second pump to get the head pressure up. If that's the case, the following are easily available:
(I would be going A64 unless someone suggests otherwise - the Dothan chips from Intel look interesting...)
DTek LRWW
Any Dangerden stuff (RBX, TDX, silver, copper)
NexXxos
Polarflo
The impression I get is the LRWW, RBX and Storm are the best blocks right now (please correct me if I am wrong!), but I would rather not order the Storm outside the UK.

EDIT - are we allowed to discuss UK shops for WCing? I frequent a UK forum where this is strictly forbidden, I'm sure you know which one I mean. Trying not to be elitist, but it tends to be full of n00bs these days. I'm trying to get my info from here and xtremesystems now. Also, is there some sort of rivalry between Xtreme and here? I noticed a few threads about banned IPs and what-not. Just so I don't mention anything I shouldn't in future!
