It looks like Byteware has a refurbished Sony notebook computer for only $1000. The only component of this notebook that may not work in Linux is the winmodem and memory stick reader. The onboard Radeon video should work with the open source driver with full DRI 3D acceleration (unlike the onboard ATI mach64 in my Sony Athlon notebook.)
