Thanks to some excellent suggestions and great help from Joe/N5KAT I 
did a lot of looking into ultra low ESR capacitors and in my 
searching came up with some excellent sites relating to the same. 
Here are a few links that help one to understand electrolytics better 
than most texts would give;

and

Here's Sanyo's varieties of caps:

Here's Sanyos' Oscon line or ultra low ESR caps. You'll have to 
search through the pdf files to find the ones that you're interested 
in & the voltage, size & ripple factors are listed for each cap & 
you'll see these new ultra low ESR electrolytics are like the old 
school caps on massive steroids:

This is just the Sanyo brand information. There's others such as 
Rubycon & NIC that make Ultra low ESR caps to investigate.
