I'm looking for high capacitance (at least 5000), high voltage (at least 35 V) electrolytic capacitors. Digikey lists Panasonic ECG series. Are these good? What are some other _reasonable_ alternatives? Thanks!

hi, could somebody answer my silly question: what do you use to drill holes thru steel and also aluminum enclosures? i had used a Dremel at high speed, in order to drill thru a RadioShack aluminum case, and the bit was all destroyed by the time i finished... thanks!
