Bill,

You might look here:

Believe it or not, Radio Shack can order the Eveready 30V battery for you and have it shipped to your house for no shipping charges.

I was just trying to come up with something that doesn't use batteries.  I always have that fear of them leaking, etc.  I do like the 4 x 9V solution, though.

I finally found the schematic and see where the 30V is only needed on the highest ohm scale so I might not even fool with it.

Thanks guys,
