Digital BW, The Print

Hello,

I am just switching - or considering a switch to digital printing. I shoot medium format 
B+W exclusively. After having a few scans done on an Imacon, I think I'll continue to scan 
my portfolio of negs. I seem to need no more than 3500-4000 DPI for my 6x7s. 

My question is what scanner to buy - Imacons are not an option (Im a graduate student). 
I've looked at the Nikon 9000 - but have heard only bad things about its neg holders. The  
Minolta Dimage Multi Pro looks great, but is hard to find. 

I would love to know which flatbeds with tras units you like and also am interested in 
hearing about the new(er) Microtek 120tf. 

Thanks for your time,
