Hi There,
When our company was first starting, we bought a Sager notebook to do demos of our product -- our experience was extremely good, to sum it all up. We got a Celeron 466 processor and 198MB RAM with a 15" LCD screen for just over $2000 (this was a little over a year ago). To get a "name brand" machine, it would have cost us more than $3500.
The only drawback has been the machine's weight, but that hasn't been a big deal for us. We even got NT working, but it came with Windows 98 installed.
Good luck!

P.S. We ordered directly from them, and that worked out great.
