I don't know, you should join and ask. ;')

I've used whatever Radio Shack sells and found at best
it is adequate, at worst a waste of money and time.
I've also used some dry stuff I think was Ammonium
Persulfate that I was satisfied with.

A colleague told me he's used a weak Nitric Acid mix
to etch boards -very- quickly but you have to be well
rested, have a lot of ventilation and really be paying
attention. And your etch resist coating had better be
complete.
