getting a new laptop

I’m getting a new laptop (hopefully), and I have some questions.
I have a very short budget (a tad under $800), so I’ll be buying from Ebay.

one of the 2 auctions I have my eyes on is a Dell Inspiron 5150 pentium 4, with a 32MB ATI 9000 Radeon video card, and the other is an Acer Aspire 1662 pentium 4 (same speed), with a 64MB ATI Radeon 9700 graphics card.

so,
-has anyone heard of Acer,
-if so, are they any good?
-which sould I get?

Acers are meant to last atleast 5 years

Dell has good support.

Pick your pony!
