I have to admit I am still an old fart of the Big Clive era and make my PCB's with all the ghastly chemicals, and tools, and spare FR4, (but not that PCB guillotine - so jealous).
My FeCl3 is like a Spaniards sherry bodega. It really needs to be disposed of in some kind of hazardous waste at some point. So I keep recycling it instead.
I know once I get a stack of PCB's from China I will be addicted like crack, but in the meantime I am amazed I can make double sided boards with household chemicals and yet all my clothes and work surfaces are stained in a sick brown and orange colour.
