My etrex vista came with a serial cable, I later purchased a serial+power cable for it off of ebay. The usb-serial cable I use to connect that to my notebook came from some Compusa, BestBuy, or possibly even walmart.

I use an etrex vista, works well but I have to use a USB to serial converter as my notebook lacks a serial port.

I live in Gaines County where Seminole is. Have a bunch of friends in Midland/Odessa (PBLUG).

I live in West Texas, but just finished visiting some family in Copperas Cove.
