Digital BW, The Print

I'm a posting newbie, though I have read the expert comments on this
forum for quite a time. I have a question, that has probably been
answered before, but the sheer volume of posts is proving to be a
daunting challenge.

Simply put, I'm looking to produce THE definitive BW print. To date,
I've been using Photoshop successfully, but I'm constantly looking for
ways to improve my BW prints. 

I currently scan film mostly with a Minolta Dimage 5400 and then use
Photoshop for custom workflow. I use a trusty Epson 1160 for my 5x7,
8x10 prints with MIS Quadtone inks and, sometimes, Paul Roark's
curves. If you need to see the type of images that I'm printing, check
out my website: http://www.mikegerra.com/index.php

I'm trying to determine if I can get the next level of BW print by
using a RIP such as IJC/OPM or QTR. Or, if my pennies would be better
invested in a printer with finer droplets (such as Espon 4000) and
sticking with PS and my curves. 

Many thanks,
