Digital BW, The Print

Does anyone know of any samples comparing prints done
using the the various MIS inksets to prints made with
the stock color inks available on the web somewhere?  
Something that will give me an idea what the differnces 
are and what I can expect to get from the MIS inks vs. 
the stock inks?

I am specifically interested the EZ inksets for the 
Epson C84 and the UT set for the 1160.  I don't own
either printer (although I do own a C80, which they
don't support) and would just like to get idea of 
what the results will be before laying out the cash 
for both the printer and inksets.

Thanks much,
