looking for dei cable for 1100f

pretty much sums it up.. we've got tons of these new 1100f's at best buy, but no way to change programming from the base ford/mazda platform. i know best buy won't provide the cable (or the computer for that matter) but i would really love to get ahold of one. i've got an old pc collecting dust at home, so i plan on installing that into my toolbox.. once that's done, i just need to install the software (will have to source that myself as well i guess) and we'll be able to actually use these things.

does anyone here know how a person could go about getting this stuff? is it something i'm gonna have to get with a rep on?

thanks in advance guys.. i appreciate it
