SX-1010 Main Power Supply Caps

I just purchased a SX-1010 and want to replace the two 18000uf 63VDC caps. Being a "newbe" I need some guidance in selecting the replacement capacitors.
In searching the web, I located 2 possibilities. The first one is a pair of CDE 70V 18000 uf Computer Grade Caps from Capacitor 12 for $70.00. The second is a United Chemi-Con Part # E36D750MLN183TC79M 18000uf 75V for $12.68 each at Digi-Key. They are labeled "General Purpose".
Is there a reason for the considerable difference in price ($35.00 vrs $12.68 each)? Which should I select or is there another choice I should select?
Thanks

Chemi-cons--Are these the same diameter/length as the original? If they are..I'd get them ordered pronto.Digikey only has 4 of them..

When you've measured them could you let me know if they match?
 
CDE thinks a little too much of their caps IMHO. The UCC caps are excellent quality.
 
Thanks for the info!
Yes, the caps from Digi-Key are the same diameter and maybe 1/4 inch shorter than the original caps. The order has been placed.

I think on one of the threads someone mentioned about installing a smaller cap in parallel with each the main caps. I can't located it know. Anyone enlighten me as what this was all about?

Thanks againg guys!
 
The idea is to put a good quality film cap across the terminals of the big electrolytic caps...something between .047µf and 4.7µf 250V, 2.2µf being a common value...to lower the impedance of the cap at high frequencies. Your call on whether to do it or no.
 
EW, could you give me an example of a high quality cap? I would not know the good from the bad.
Thanks
