Considering all the discussion about cartidges lately,
I was wondering what the prospects are for building
an inexpensive multi-port extension that would allow
those who need the port for more than one application
to not have to turn the machine off.. reinstall "another"
cartridge or dongle etc.. Doing this on a regular basis
will only ask for problems.. guarranteed damage to the 
port and to the cartridge or dongle.

Specifically, I would like to get the GCR.. I also use
NOTATOR on a very regular basis.  There are other
commercial products requiring the use of the cartridge port,
obviously...  I assume building a cartridge extender is
difficult and costly.. otherwise there would be one on the
market...  C-LAB puts out "The Combiner" for $349.00.
Seems a bit pricey to me!  

Does anyone know of another in development.. or already available
that is reasonably priced?
