i’m also looking for a laptop in that range, indeed popped into the local comet this morning to see some ‘in the flesh’ as it were.
what struck me was that, on the face of it at least, there was’nt a massivly discernable build quality difference between so called budget brands like acer and the more expensive toshiba/sony etc. the nastiest looking/feeling one was quite a pricey toshiba, i was surprised.
argos have a deal on a sony for under 400quid, decent hd/ram but its an older processor. comet have quite a good looking deal on an acer (5735 model i think – i can check if you need the info) with a 2 core duo processor, 3 or 4m of ram and a decent hd. at about 380 it stands up well pricewise against the www based sites.
also have a look here…
