So the web-heads list discovered a lovely little web shop called Abate Electronics. Apparently It is possible to purchase a number of Ghost and U.F.O. detectors there. The best part of all is that they come with a warranty!!! And I quote: "ALL DETECTORS ARE WARRANTED TO OPERATE AS DEFINED FOR A PERIOD OF ONE YEAR FROM THE DATE OF PURCHASE. ANY DEVICE WHICH FAILS TO OPERATE FOR THIS PERIOD OF TIME WILL BE REPLACED FREE OF CHARGE, INCLUDING SHIPPING."

I hope the meter is wired to ground. Otherwise any blip they produce will be detecting something that is almost certainly not there. How do you collect on your warranty? I can imagine the exchange now:

You: Your crazy meter went off when there were no aliens.
AbateElect: How do you know there were no aliens?
You: There was a distinct lack of bright lights and probing.
AbateElect: Maybe they were hiding?
You: Hiding?
AbateElect: Yeah, like invisible!
You: I give up.
