SR3: How to steal a cyberdeck?, Are you ready to rack your brain on this one?! Options

[Mardegun]

Goal: Present a plan to my GM detailing how my character can steal a cyberdeck.
Main Question: How to find a mark to steal from.

I am in a 3rd edition game with a character who wants to become a decker. After looking over the rules it is very clear that the cyberdeck is the single most important element to being a good decker.

So I am asking for help from the dumpshcok community in thinking of ways to steal a cyberdeck. The why isn’t as important as the how to making this happen.

Here is a little about my character.
My character is a face adept with skillwares. I play my character a lot like SOPHIE DEVEREAUX aka The Grifter from the TV show the Leverage. The main differences are my character can truly look and act like anyone; his powers are Kinesics level 3, facial sculpt and voice control with a disguises skill and off course high etiquette and negotiations (aka Con). My character being the face of course also has lots of contacts, 14 in total. So with assets like theses how would my character go about stealing a cyberdeck???

Problem 1
How do I find someone with a deck?

Being that cyberdecks are illegal that narrows my search done to

A. Shadowrunner
B. Corporate decker
C. Young kid with rich criminal ties??

Anyone one else have a good suggestion? Now for each one of these how would I find an “easy” mark? I really need help presenting a good solid plan to my GM on this. I have some ideas, but I want to hear what you guys come up with.

Thanks in advance,
