Yes, it I know from experience it does require a fair bit of work 
to make a spray etcher. Obtaining a pump and is not a problem, 
nor is the cost. Most of the work is designing/building a sealed 
chamber and the mechanism to move the nozzles about. But since 
I've gone this far it would be silly to stop now :)
Note, I had to buy a $300 plastic welder to make these tanks, 
plus go through a big learning curve working with plastics (PVC).
