As previosly said hun - dell are very good specification and price wise, other ones like advent, tosh, etc are all fine.....youy can take a chance with a cheaper / non main stream branded laptop as MOST of the parts you can service (HDD / RAM etc) are generic, but its the warratny on the main system board that you will not get as good cover with others.
TBh a nice cheap dell would odo you perfect, doesn't need to be top end spec for browsing / emailing etc.
