Best Alternatives to Black Gate Caps

Does anyone have an idea as to the best cap alternative to the Black Gates that are no longer available?

Specifically 3.3uf 50 Volt.

I would fall back on the FG or the ES (which is bi or nonpolar). Odyssey Audio uses ES series for their "upgraded parts" amps.

(http://www.partsconnexion.com/t/catalog/CapacitorsElectrolytic.html) I wish Sanyo would produce their OS-CONs in higher voltages.
