Homebrew PCBs

Oh lordy, I sure didn't want to get into chemistry when I started 
tinkering with electronics, but that is just the way it goes sometimes.
I will be using up my FhCl till it's gone which may be a long time, 
but, trying to figure out which to switch to is confusing me.  I have 
started a comparison list below and am not even sure if what I have so 
far is accurate.  Clarify it if I am wrong, add to it if there are 
attributes I missed.

FhCl 
 Advantages - 
   Easy to get, Radio Shack

 Dissadvantages -- 
   Can't see what is going on inside the tank
   Stains everything it gets on
   Disposal - flush down the toilet?
   Somewhat slow process (in my few experiences)


AP

   Clear in color
   Does not stain

 Dissadvantages -- 
   More difficult to obtain
   Cannot be rejuventated
   Disposal - Not sure what to do with it


CuCl 
 Advantages - 
   Does not need a heater
   is somewhat clear in color?
   Can be rejuvenated

 Dissadvantages -- 
   Difficulty finding the high concentrations chemicals
   A little more complex in use to maintain (but lasts longer)
