In answer to your other two questions:
1 Duo keyboards are notoriously crap. Spongy, failure prone, generally ick. The screens however are very nice, but given to fading at the corners. Docks and minidocks are not too hard to track down, as vintage computing accessories go. The Duo 2300c will take either SCSI or IDE internal drives, and has a 100MHz PowerPC processor.
2 2400s are rare and expensive. Better off spending the money on a Wallstreet.
My recommendations: 180 series (built like tanks) 190 series (take PCMCIA cards) or a 520/540 series (heavier but lots built in). In each case SCSI internal HDs only, unless you use a CF card in the 190's PCMCIA slot.
If you want a good all-rounder that takes IDE drives, go for a 1400 series. Great keyboard, PCMCIA slots, adequate PPC processors and (rare-ish) upgrades to G3. Try for a 1400c screen- the cs is not quite as nice, but adequate. Apparently there is a greyscale version, but I've never seen one.
In all of the above cases, try for a machine with the most possible RAM, as it's proprietary and relatively hard to find.
Next step up: Wallstreet G3s etc.
Are you planning to use this in Iraq?
