I just got my EVSPK a few weeks ago. Didn't come with that package. What you're describing sounds like the RA1165 undertable base. I was thinking about buying one but wasn't sure if it'd be worth the extra $50. I sure wish you could just buy the parts to convert the standard fixed base, but Bosch won't even release a parts diagram for that new undertable base (I called). I *THINK* the only thing different would be the adjustment shaft extension and you'd need to pop a new hole in the base. Other than that it looks like my fixed base with no wooden handles.
