Value of this laptop

I would like to know how much this used, about 3 year old laptop should sell for.

It’s a Toshiba Satellite 3005-s303

pentium III 850mhz
256kb on-die write-back level two cache
100MHz FSB
32 bit PCI card slots
512MB of pc100 SDRAM
GeForce 2 Go graphic card
3 hours battery life
20 GB harddrive
switchable floppy and dvd/cd-rw drive
14.1 inch TFT monitor
windows XP home

I would like to know the dollar value, because I would like to see if it adds up to about an iPod 20 gigs, with 20 dollar case, and iTrip, all bought within three months.

Thanks,
Toasty
