Digital BW, The Print

I'm thinking of buying a spyder or other hardware calibration tool.  I'm
currently running a Dell 2007FP monitor with a epson 1280 with UT2
inkset, using a couple of different papers (costco kirkland and red
river aroura).  I'm looking for a cheap and (mostly) easy way to do
calibration so I've got a fairly good wysiwyg environment.

My question: Does black and white printing favour any particular
hardware calibration tool and, if so, can anyone give some suggestions
as to what I should be looking at getting?

Tia,

Chris
