The Digi 002 has the capability to add 8 more ANALOG inputs through the optical digital input.
To do this, buy something like the Behringer AD8000, and two ADAT cables. Then you'll have 8 more ANALOG inputs. I know this has already been explained and mentioned several times in this thread... this really is your best affordable solution.
Note that it's pretty common nowadays for gear to have 16 or more inputs, only 8 of which are analog. ADAT inputs are on just about everything now, and everyone refers to them as "inputs"--whether they are digital or analog.
