David,
You should consider your end product. An AZO print cannot be duplicated digitally, nor can platinum or even glossy fiber base.

Much of your work seems to be large format; it will be a long time before an affordable digital sensor will equal what you can do now in terms of resolution and accutance.

Last year, I finally got a sink in the same room as my enlarger, a world of convenience compared to using the ajoining bathroom!

Go for it!

Take care,
Tom
