Selling my old PC's and Buying a new one?

[dyeownsme]

Wanted to get some advice on selling my older computers to get some money to buy a new laptop.

I currently have a
E-MACHINES T3414
346 Intel Celeron D 3.06GHz 533MHz FSB 256 KB L2 Cache
DVD/CD-RW drive16x/48x max.
80 GB HD
256MB + 1.0 GB
S3 Graphics UniChrome 3D Video
Includes:
5.1 Surround Card
Wireless Card
Keyboard, Mouse, Speakers included.
(Also have ACER AL1914, 19in LCD)
-----------------------------------
and a
Dell Inspiron 6000
17in. LCD
Processor: Intel Pentium M (1.6 GHz)
RAM installed: 512 MB DDR II SDRAM
Weight: 6.6 lbs
DVD R/RW + CD-RW drive
(4) USB
Includes Charger
-----------------------------------

I know they not worth much but any idea of how much to sell them for would be great.

Finally I would be using that money plus more to find a new laptop, I only use the internet and limited autoCAD.
Good picture is a plus, durability is a must but weight is important my dell is heavy.

Thanks for the help

Looking on ebay, the laptop is getting between $150 to $250 for working ones (those are actual bids). The emachines didn't come up with any hits, but is probably in the same range or slightly lower.

I sold my similar spec laptop (compaq) to a coworker for $200, and that was a steal (for him). $250 sounds good.

I had a T29XX emachine tower, it was only like $100 after rebates, day after thanksgiving sale. I doubt you'd get much for it, $100 might be reasonable.
