I'm planning to build my own version of the Nova processor. I suppose it can't be too hard to cobble (or chloroform, rather) together some acrylic pieces. It shouldn't cost too much either. Has anyone done this before?

I considered using a drum system as well, but I figured that it'd be more expensive as the equipment isn't available locally (i.e. I have to order in from the USA or UK). Unlike the Nova which I think I can build fairly easily.

I just got a few books from the local library on darkroom construction.
