Best UK Seller

i think this is in the right forum...

anyway.. im soon to be buying a budget pc, at around the tune of £550, and was wondering if anybody here could recommend a seller in the uk?

so far i have found www.overclockers.co.uk and www.scan.co.uk to have very good prices. Does anybody know a better one?

thanks

edit: or maybe just point to a similar forum to this one that is centered in the uk, if nobody shops round here?
