Digital BW, The Print

I was curious if anyone is using a scanner as a make-do densitometer. I was
reading Bob Wheeler's article on digital zone system and got to thinking
about this:

I'm interested in doing some zone system tweaking and trying out the Bowhaus
software. Probably on the 2200, or whatever comes down the pike in the next
2-3 months.

I see that you can get reasonably priced transmission/reflective step
tablets here:

Kodak's targets are considerably more expensive.

I realize that densitometers are going (relatively) cheaply on ePay, so
maybe it is moot, but if I can keep one less piece of gear on the desk, I
would be happier. I would be doing this with the Epson 3200.

Anyone have any suggestions?

Also, any of you that are familiar with densitometers, can you give some
recommendations?

Thanks!
