What should I pay for a Rev A Mac Pro

[Bourne-Here]

I am looking at a Rev A Mac Pro with the 2x Dual Core 2.66 Ghz 5150 chips, 1GB 667 Mhz RAM, 250MB HD. (the standard model from August of 2006).

I am told his comes in the box, but It does not have the keyboard or mouse.

What should I reasonably pay for this machine?

Also, I'm planning on upgrading the RAM.
Is there any problem adding 2 2GB chips to the existing 1GB (5GB total) or should I just pull the 1GB chip?

Thanks for helping a Mac noob.

$1000? Or check this to see what a good baseline would be.

Thanks Jessica... Mac2sell indicated $1,620. I'm paying closer to your price, so I should be in good shape.

$1000 looks good...or max $1100
