Digital BW, The Print

Thanks for the help everyone.  I'm leaning towards the R2400, I think its
the better fit.

Anyways, have I read correctly that some of you are using MIS cartridges for
the R2400 and refilling them with ink from 4800 carts?  How easy is this
(I've done the usual cheap-o ink refilling on an inexpensive desktop
printer) are problems common? Is it recommended?  It looks like it can save
a huge amount of money so I'd like to do it.

What would I need to buy/where?

Thanks again for all the help!

BTW...is a member by the name of Bill K. still around?
