I wouldn't worry too much about H2O2 availibility. The pcb makers are a 
very small minority, then the authorities start setting the availibilty 
rules, they will have to listen to a very loud bunch of housewives.!

Let's be realistic, there is a difference betwenn buying a single liter 
and 200.

For etching you really don't need the 30% H2O2, it results in a very 
violernt reaction. I found out the hard way.The standard 3% is just 
about the correct diluted strength. Yes, a stroneger versioon is great 
for regeneration, but the stuff is so cheap anyways.
