Homebrew PCBs

I was staying away from the professional kits because I was trying to 
document what works with
the most readily available and cheapest chemistry so ANYone could repeat

and avoid my failures. ....  so we could etch short wave radio PCBs with 
kids...scouts.... newbies....
DIY...makers....  anybody.... without spending $75 on a "starter kit".
