include both.? The PDA that I am using is a Sharp Zaurus SL-6000 therefore equipment compatible with Linux and Kismet, and i would like to use Netstumbler for my laptop.

I know the equipment I need, but I would like to know the best Wireless NIC, the best Handheld GPS Unit, I would prefer one of the small ones that only work if connected to a computer, and the best external antennae.
