Homebrew PCBs

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.
