Digital BW, The Print

You may remember my post about getting a defective R2400.  Well after nearly a month of 
tribulation, I got my new printer.

It was worth the wait.  I am blown away by this thing and I haven't even begun to learn 
how to take control of the thing.  I'm very excited about this.

Now, of course I'm looking to build myself a nice "digital darkroom."  I am operating on an 
old G3 iMac!  Yikes.  So, I know enough about the computers to know what I am looking 
for.  The main question I have is what kind of monitors I should be getting.  Should I be 
using CRT or LCD?  Can I get a monitor for a PC and use an adapter or is that going to give 
me calibration problems?

And finally. . . (deep breath) if I get a G4 will I need to get some kind of card to drive a 
second monitor?  If so, where should I be looking for that?
