Homebrew PCBs

Hi guys,

I have been using Ferric Chloride for a few years now - works fine 
and is easy to get and dispose of when spent.  The downside is the 
mess.

I know there are a couple of other options out there and am willing 
to give something else a try but am hesitant on two accounts

1) I am not a chemist
2) I don't want to kill myself

Of the options that are available, which is a simple product to use 
AND maintain?

What are the drawbacks to these other products (chemicals)?

I am a bit concerned about the gasses given off.  I etch in my garage 
which is filled with machinery of which I don't want all rusted up.  
On nice days I work outside, but during the winter I etch inside.  

Smells can be another problem.  After smoking for 25 years or so and 
quiting, asthma and other respiratory problems are an issue.  

So, if you have experience with other chemicals for etching, I sure 
would appreciate hearing about your experiences and opinions.

Chris
