Adam, there is an easy way how to make such (cheap & reliable) etching tank,
(if you use Cu/Fe Cl based etchant). If you are interested, i can send you pics & drawings.

My spray etcher works great, and it gets used all the time. The reason I
was interested in more reliable bubble etching was part of another
project to see if its possible to fabricate a compact and complete PTH
PCB station for fabricating 150x150mm boards. If it is possible to get
cost and labour down to a reasonable level then I would look at
marketing such PCB prototyping stations.
