Hmm hard one this, Dabs, not a good word to say for them and personally I would never order from dabs again in my lifetime. E-Buyer is cheap and cheerfull, if what you get works your onto a winner.
My vote though Goes for SCAN (
www.scan.co.uk) cos ive never had a single problem with them ever, even a graphics card that had died months later and they sent a new one and picked the old one up at the same time - cannot say fairer than that tbh.
