I am looking for a 12 volt programable timer.

As a less expensive option or if you need more amps you might try one of the Phoco CX series charge controllers. These solar controllers can be simultaneously used as a load controller. That is you can connect up a DC load (as long as it's not over the capacity of the controller, 10, 20 or 40 Amps) and program it to shut off or on whenever you want.

Check them out here:

Coming very shortly is a new interface for these controllers which allow you to connect them to a computer to program. Really cool and easy to use interface (USB).  In the interim you can program it through its simple interface on the front.

Best of luck!
