Hmm - difficult. You could look at the Which reports for reliability; call centres I'm not sure about, but when you buy something, the onus is on the seller for repairs/warranty etc - not the manufacturer.
I think these are always worth considering Click Here and are available at a couple of supermarkets, I`ve had one of their Desktops
for nearly four trouble free years and have also got a decent Netbook
I have read that they have good after sales service but have never had to call them, at the end of the day its your money youre spending.
Good luck with your eventual choice.
