Homebrew PCBs

I would be interested in getting a good idea of what
are the etchants being used.

AFAIK, they are :

1. Hot FeCl3
2. Muriatic Acid + Hydrogen Peroxide
3. Copper chloride

And I got that hopefully, in order of popularity.

If all these work, the 2nd choice seems to be easier
to get and use; so why is the first so popular.
I myself use it, and the reason being people I know
who do it professionally use it too ?

What's the reason? Financial? (The 2nd choice is a
little bit cheaper than the first) Speed? Ease of
storage?

I would like to find it out from you, and do give
feedback of what all etchants you used and what you
finally settled with and why.

Cheers
