My Black & Decker cordless screwdriver died

The battery to be specific. I can't find anyone who carries them any more, so I can't get a replacement. Or at least not easily. So why not take it up a notch:

Didn't cost much more than the B&D tool I bought before, but has quite a bit more power. Plus it has 30 levels of torque to avoid stripping screws but still allow for the power necessary to get the job done. Didn't have a hex driver bit, but my B&D bits fit in the adapter just fine. And a tool like this is required for any Ikea project...
