I had a cheap one from Edmund and it worked really great!  The amplifier
was (of course) pretty simplistic and the pickup wasn't much better, but the
results were quite good.  Apparently the dish was designed well.

I replaced the mic and used a real amp, then the results were fairly
amazing (interestingly the mic was from R.S., but at least it eas a Shure.

The new catalog has a greatly improved version:

Bionic Ear (tm)  H33,595   $129.00

They claim it can here a whisper at 100 yds., I'm inclined to agree.  It
also has an auto gain which will mute loud sounds before it gets to your
ears (a _very_ good idea).
