Source for teflon caps

I have a bunch of Vcap Copper teflon and Tin teflon around, as well as Russian FT3,K72 Teflon, Sonicap teflon, etc, and while the best of them are fantastic, I don't see the need to pay so much when you have fantastic-sounding modern caps like Jupiter copper foil and Miflex copper foil capacitors for much less money.
