I just got a brand new Dell Inspiron 9100 with a few extras added. Granted it is a high spec lappie, but brand-wise they seem to be excellent.
Screen is extremely sharp and clear, i have 1 years insurance against everything, and Dell do a pick-up and deliver if it needs fixing.
Best of all they do (or were doing?) a 'buy it now and we'll do double the RAM for free' deal on all laptops. Got 1026MB now which is nice
Id rate Dell, definately... saying that, Ebay can be just as nice!
