i think most people thinks that nothing beats the manual B&W.
But try AGFA's new dLab2 machine, there are two in Singapore.
One at Chinatown point and one at peninsula plaza. The one at peninsula (d2 Digital Centre) also belongs to Konota that's next to it.
They personally have a sample between a manual B&W and a digital B&W for you to see.
I know because.. I work there.. hahaz..
Unfortunately different people have different ideas what "excellent" and reasonable" means. The market is such that most prices will be very similar. Go to Ruby or Ron's and see if the black & white prints are up to your expectations, then talk about prices.
You may also like to consider what ben86 suggest by going the machine way. I may go there myself to have a look at the Agfa prints. I saw some machine B&W prints in Ruby. They are nice, but in my opinion, still a far way off from a traditional B&W print. The question therefore bomerang back to what you consider "excellent". To some, an excellent Hi-Fi system is an AIWA set. To others, well! I dread to imagine!
