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.

Hi Steve,
What etching fluids are used by your
group members?

Malcolm

I've started a Yahoo Group on making, etching,
soldering printed circuit boards yourself.
