I’ve long enjoyed my 2 year-old Wi-Spy. I see they will soon be coming out with a Wi-Spy DBx “soon” for $799. If you sign up, I guess you get a coupon for $200 off when it is released.
Sadly, the price point moves this out of the “geek gadgets” realm and into an area meant for people who professionally test, monitor, or manage wireless networks. I actually do not manage a wireless nework at my current job, so this gadget would really just be a for-fun deal. Even with the coupon, $500 is too high for a toy for me. But I wanted to mention it to remind me it is there, and give someone else the idea if they could use it and afford it.
