Can anyone tell me the difference in capacitors. Such as the quality control in producing it, the testings, the specs (low esr), brand names, and if its worth buying a 30 dollars 1.5 farad capacitor v.s. a 170 dollars 1 farad capacitor.

thanks

thanks for the information, and averagesupernova, i'm not into car audio. I know that majority of the people who purchase cap's are into car audio, but i'm doing a design project that need a cap to have an actuation time of less than 1 sec.

Well, if you need the capacitor to have a discharging/charging rate of 1 sec, you need to evaluate:

Time Constant = R*C = Time to reach 63% of final value

Hmmmm. Actuation time meaning what? More info please. Depending on what you are doing, the ESR and other things might not mean a darn thing.
