Be sure to keep this in mind... the chart that I linked to above is typical for new caps, some increase is normal over useful life. Caps that have 10 times or more than typical new value are suspect.
I have even seen new (cheap) caps that were about 2 times the value stated on the chart and they seemed to work ok, while higher quality brands usually beat the chart number by a significant margin.
