I use Edinburg etch with food grade citric acid.  10 minutes to etch a 6" x 4" board at 30'C.  6 years old and still going strong, etch time has shortened a little.

       I am right
 back to square on not being able to afford proxion and am
 looking at carbide drill and press seen at jameco.com but
 with no spec sheet. Jameco.com seems to be a good site,
 company ect. My peroxide bought at dollar store is the cause
 of long etch times. Has any one tried the edinbourgh etch
 method? Will food grade citric acid like ones sold on
 amazon.com work ok?
