I bought a long steel bolt from the hardware store, and used two
steel nuts to fasten a piece of wire to the bolt.  I then siliconed
the assembly to make the wire-bolt contact waterproof, and was in
business for a total cost of $3 (US) or so.

I keep the wire-bolt contact a couple of inches above the high 
water mark in the tank, and I have not had any trouble.  The 
gizmo has been in operation for several months now.

Of course, this is not recommended for salt water use.
