You're on the right track.  Get the highest temperature rating 
available (which is probably 125C), buy only caps manufactured by one 
of the known-good manufacturers, and select from a parts series the 
manufacturer designates as "high reliability" (or equivalent).

If it is a solid tantalum, I like the Vishay 199D Series.  The AVX 
TAP Series and the Kemet "T" Series ("UltraDip II") are also high 
quality.  (This list isn't exhaustive -- these are just the ones I've 
had occasion to qualify.)

Best regards,
