No, not that bank!

I'm using my P3 for solo work, band work, and live work and have
gotten to the point where I'm having to regularly shuttle my banks off
and on to memory from sysex files on my Mac computer in order to work
with the applicable banks.

I'm wondering what others do in order to manage a number of banks
larger than the internal memory will allow? 

I wish there was something like a MIDI memory stick that could plug
into a MIDI port for bank dumps or a Flash ram card that could be used
for expanding available banks.

Not expecting the above, what techniques do you use?
