Digital BW, The Print

I've researched myself into a corner. I've read about Piezography, 
MIS, Quad Tone RIP, Black Only printing and now I'm really confused 
as to which way to go.

K.I.S.S. was created for me. I'm not all that stupid, but I like to 
keep things "simple." I'm not too technical. On the other hand, I'd 
like to obtain the best looking print I can. I know, it's hard to 
have both. At any rate, my priorities are:

1. Image quality
2. Simplicity of workflow
3. Longevity
4. Cost
(Have I overlooked anything?)

Some of these systems appear to be very complicated, more so than 
wet darkroom printing ever was. So if any of you have a suggestions 
and/or opinions on this, I'd love to hear them.

Thank you in advance for your guidance!
