Slight nitpick, if memory serves the Fuji process is CN-16S (though I may be wrong - it's been many years since I ran a Frontier minilab!). To all intents and purposes it's regen RA4 though.
The big problem with Frontiers was it was near impossible to fully eliminate the colour cast on B&W prints. You can kick the machine into B&W mode manually, but there are still limitations the RGB laser exposure engine and process puts on you. Practically that means you can't get a true black like you can with silver-halide processes.
They are still fabulous machines though. Awful user interface, but the technology behind them is pretty incredible.
