Digital BW, The Print

At the risk of asking something that's been covered endlessly on this 
forum....

I'm interested in bulk inks (is that what they're called?) for my 
2200 to save on cost.  I'm looking for standard inks that will match, 
as closely as possible, the OEM inks provided by Epson.  I print both 
color and b&w, and my printer already has custom profiles based on 
the Epson inks.

Rather than asking everyone to repeat what's already been covered, I 
wondered if someone could point me to a link that discusses and/or 
compares my various options.
