Can anyone suggest/recommend a device to detect the presence of public

in order to find out if there are any hotspots nearby?

The ideal device should be small, have a display that shows the name(s)
of the available nets if any found, and be cheap...

    

The original Kensington WiFinder got lousy reviews when it first came out:

However, there is a newer revision available. The WiFi Finder Plus ( http://us.kensington.com/html/5703.html ) seems to be a better gizmo than its predecessor:
