4x3 sealed membrane keypad

I’d like something similar to http://www.sparkfun.com/commerce/produc … ts_id=8871, but just in the standard 4x3 layout. http://www.seeedstudio.com/depot/sealed … p-132.html is a 4x4 version. Ideally, I’d like less space around the border. I’m trying to find a keypad to use with a case like the Serpac H-65 (http://serpac.com/Products/Hseries/h-65.aspx) with 2xAA batteries. The Sparkfun 4x3 matrix keypad is too big because of the battery holder on the case.
