Punisher Max is a good Shadowrun "Sourcebook" series, as well. It shows a person living under the radar with insane amounts of firearms and how he does it smartly. Also, it demonstrates various forms of surveillance, tactics (Not sure how good they are, but hey, better than what you see in the movies!), and just how much ass one person can kick when really pissed off.
Not just Max. There was a short run Punisher Armory series that greatly influenced my Shadowrun thinking back in the day.

Yes, but it is very, very,
VERY hard to find them now. It took me... Seven years, three cities, and a trip to the US to get my collection.
Very useful, however, and does give a lot of ideas, as well as image ideas for weapons and other equipment that Shadowrunners might use. Especially considering that they're likely to be working "On The Cheap" so the High-End (Or beyond, as we are talking "Microchip-Aided Punisher" here) Equipment he shows off would be in the Discount Bin at the Crime Mall, perfect for Shadowrunners to use.
In addition, a few pages are dedicated to training and "Off Time" practices which are great for characters to take into consideration between 'Runs. Too many GMs forget that there are often weeks if not months between Shadowruns at times. What do the characters do with their time off?
One of the rules I implemented was that everyone had to have at least one knowledge skill that was a "Hobby Skill". The Pre-Fab characters come with one, after all), and if they don't explicitly state what they're doing, that's all they do.
"Wait, you spent all month watching
JUST Urban Brawl?"
"Sure, the College Playoffs were happening in Russia. I had to pirate a LinguiSoft and I don't think I understood the announcers too well, but it was really interesting how the game is played over there, did you know..."
"You can stop talking now. Really. Stop. I have a Uzi."
