Mark: The cost of capacitors is probibly the single largest expence in time
and money. I have used a veriety and found the cost about the same if you
consider labor as part of your cost. In parts alone the salt water cap is
the least, the wrapped poly second and the geek group next. The commercial
discharge cap is in a price field of its owm. Two of my caps cost over $1000
US each. The question is asked which is best? That depends on your
application and brings up a rash of "my way is the only way" comments. I
like the wrapped poly/alumunum plate cap. The Geek cap assembly is real
convient and clean. The salt water bucket cap is messy, large and least
expensive, but time to maintain is not viewed here. Each type has it's
best" application and it's limitations. I suggest you start with the salt
water cap with it's low parts cost and high labor/space cost it is fun to do
