Digital BW, The Print

Hi-

I've been making some "low ball" bids for a densiotmeter on 
ebay...not enough to win (or if I do it will be a real bargain).

What x-rite models do you think are best knowing I will be using it 
to just judge density on BW not really doing anything in color?

I'm also bidding on some much cheaper Macbeth ones...

Any thoughts or advice appreciated.

cheers,

Tom O'Connell
