Digital BW, The Print

Three questions: 
-Can anyonee comment on well priced high quality Non-inkjet options. 
Like MPIX.com on B&W paper for digital.
-How does black Only on Epson 2200 and Epson 4000 compare to 
installing a Quadtone type set up.
-Most discussion in this forum is around MIS options, how does MIS 
compare to Lyson.

Thanks. I've yet to purchase a system but am getting closer.
