Thank you. :)

I knew I forgot one thing though. It's about 70 feet of wire.

I did consider a transistor, but really only as an output driver for an opamp.
I need an opamp for the circuit anyways and wanted to do a "one stop 
shopping" type solution.

Since this is a non-em application, I'm afraid going into specifics 
would be too OT though.

Thanks.
