Subject: A3 Optical Mouse reply

Hello, friend, this is Hornet0@aol.com replying to your inquiry.

Yes, I have six units left, all factory shrink-wrapped new. These are the
same ones sold by MacWarehouse for $64 something. It's not The Little Mouse
(one button and not programmable) or the cheaper opto-mechanical one that
are also made by Mouse Systems of Fremont, California.

This A3 mouse is a pure optical technology and has 3 buttons that are
customizable/progammable with the included software, a Control Panel
device.

To order, trust me and send a check for $30 + $2 (shipping/insurance) to:

Kendrick Kay
3723 Wexford Dr.
Martinez, GA  30907-4740
706-860-4114

**if you send me a check, please include a note :-)**

COD is available for an additional $3.50 USPS COD fee.
