Acernotebooks and laptopsdirect seem to essentially the same company, and having used the latter I would say they are okay. The laptop arrived promptly, but the fan was not working properly. Returns procedure is rather complicated, and involves telephoning Acer, who really shouldn't have to deal with it. Anyway, they picked up and returned the laptop with a new fan within a week.
I wouldn't exactly reccommend them, but I don't have any real complaints either. The laptops are fairly cheap, and if it all arrives working and in one piece, then it should all be okay.
