Works perfectly, passes self-test, self-calibration.
6 months right of return. Keep my contact info after the transaction.
1 year exchange/repair guarantee (that also guarantees if you take it to calibration lab in year, it will pass).
Optionally I can arrange to get the calibration certificate for extra fees, but only after you buy the unit and cut the check. It will add around 5 days of delay as I'll have to ask around for the calibration costs, report it to you, and bring the unit to the lab and get it back.
I can upgrade the old mechanical 20GB hard disk to solid state hard drive (SSD) so it boots faster and shock resistant for an extra $150.
I can upgrade the old CD reader to to a DVD writer for another $50
The pouch photographed is optional. I can install it for another $30.
The front cover is not included. I can include it for another $50.
Upgrade from 256MB SD-RAM to 512MB SD-RAM is another $30
