[sdiy] Audio circuits and basic electronics knowledge recommendation.

An entry level milling PCB router from LPKF cost more than 200 differnet 
prototype boards per year for at least 10 years. Can't remember actual 
quoted price but I remember that calculation I made back then.
And that's 200 PCBs ordered in reputable 24-hours service fab.

So unless you are not planing to make PCB making service to the public 
it's not worth buying that. Unless you work for NASA ;)

And I think laser ones is 10 times more expensive, but I never bothered 
to ask.
OTOH there are many PCB makers now from kickstarters and such, they go 
for much lower price but don't know anything about their performance.

When I need it the same day, there's toner transfer and etching. 
Otherwise I simply order top-notch quality PCB for $40 and have it on my 
desk next week. No chamicals, no glass dust in my lungs, no big investment.
