RE CEREAL keeper's for etch tank's
 
I can do 7 x 7 in board [In old money ] 180mm x 180mm
Takes about 3 1/2 Leta's of etching or striper 
OK for quick prototype boards 
 
An alternative for bigger job's keep look out for catering water boiler's
car boot sales etc.
they have a stainless steel tank and make a Verie good heated water jacket fill with water put a plastic bucket in the boiler fill bucket with echent  and they have a simerstat for heating control and usually a 2kw heater  make shaw the bucket doesn't touch the heater element there is a draw off tap to drain off the water when your dun 
Use fish tank bubbler to agitate the echent
