Have any of you found a decent off the shelf battery as a replacement for the OTS 12v NiMH battery in the SSB-2010? I could probably build one with spare cells I have lying around, but I was just wondering if there's anything out there that's cheaper than the $150 OTS wants for the official replacement. </div>
