MY experience, I've owned a DELL XPS 1530 laptop for almost 6 years now. and for the first 3 it was great. then I had to have the replaced for failure, and the mother board replaced twice, once for CMOS failure and once because the GPU went bad and it;s part of the mother board.
In general my experience with Dell is... they try. you pay a bit more, you get a slightly better product in terms of failure % and what does fail is usually fixable.
Toshiba is infallible as far as my experience goes.
My suggestion is to look at the reviews on several different sites for that modal. figure out what the failure % in those revises is and divide it by 10. that's your chance something will go wrong. you might also want to look into how many years they had owned it before it failed. they usually say.
