Nice job.
I wouldn't build such a thing for my own use, I don't like to mess around with "wet" stuff and always be worried about leaks and such.
Benta:
A better solution is a vertical bath with bubble tubes at the bottom, where the PCBs hang vertically into the bath from the top.
MosherIV:
Actually spray etching is by far the better method

I am working on a PCB printer that will print multilayer and dual sided pcbs on unclad FR4 / anything you can get the ink to stick to. Just today I received a big shipment of chemicals for producing the nano particles for the conductive inks and in the coming week or two I should have most of the other things I need.
