Digital Wi-Fi detector

A more fully-featured Wi-Fi detector is up for sale at Think Geek (via Shiny Shiny), and it not only tells you if a signal is present, it gives you SSID, security information, and lots more:

* Backlight LCD screen shows signal strength, network ID (SSID), encryption status and channel
* Provides specific information about each network when multiple networks are present
* Detects Encryption (WEP and WPA)
* Shows channel used (1-14)
* Coverage: Up to 200 feet (60m) open environment
* Identifies 802.11b and 802.11g networks
* Dimensions: 2.5″ x 2.75″ x 1″ thick (65mm x 70mm x 24mm)
* CE approved and FCC compliant
* Auto power off

Getting broadband (and wireless) connected in the UK can take a long time, and I would have killed for one of these for the first month I got here.
