[Clarence A. Rainwater]

I am also new at all this,but I'm not sure how to get my answers.I need to know 
what is the best machine
to buy(reasonably priced that is) Can you make it yourself?What is this about a 
constant current?Do you
have to use distilled water only?What if you can't get distilled water,will it 
not work?Where can I get the best
info on all this? Thanks for putting up with us beginners :>) it's really very 
interesting.
