Wow, this maybe easier than I thought - so let me get a few things clarified
here.
Sid, polyethylene - you are going to have to clarify here :-) Are we talking
about plastic here, or glass??? Or neither..

It seems from the rest of your posts that food containers are sufficient (which
is splendid - I happen to have a collection of yogurt containers that are doing
absolutely nothing but looking pretty.... don't ask).

Tony, what is bell wire, and what is the purpose of putting it in the corner of
the boards?

Basically, if I want to be cheap about this, all I need is some plastic
container, the etchant, and something to suspend the board?? The rest (heater,
pump) is just for convenience?

This is good news if I am correct, might be a lot easier, heh.

Thank you all,

Jai
