ummmm I don't think they sell Dell's at Best Buy.
But getting back to the point, I have a refurb Dell Latitude Cx500. I bought it back in March and haven't had a single problem. Runs like a champ. I took off NT4.0 and put on 2000 and it's rock stable. If I ever need another laptop, I'm looking at Dell refurbs first.
From their FAQ:
<< Q: What are refurbished products?
A: All of Dell's new computers come with a 30 day total satisfaction policy. As a result of this policy, some computers are returned to Dell.
We disassemble and rebuild returned systems to original factory specifications, then put the systems through a rigorous testing program to ensure Dell quality. We even use brand new boxes for packaging! As a result of our fantastic refurbishment process, Dell Refurbished systems include the same limited warranty as new systems. >>
