Spy Equipment and Computer Security

I recently saw a video where it explains all the techniques about eavesdropping, phone bugging and how to hack a cell phone. So i got interested in all the kinds of spy equipment out there. Scanners, Digital Recorders, Spyware Software, Data Encryption and all kinds of neat stuff... so I will be posting lots of links to places that sell spy stuff... Now some of this stuff is complete crap but some of it is not, so first thing to do is buy this video for $99 (see the link to www.tscmvideo.com , the guy that does the production is an instructor from Texas A & M (please don't hold that against him.), who knows his stuff. check out the website if you can, the video is very long but also has very good information on industrial espionage.
