Speaker surround re-foaming - any recommended or not-recomme

[Bob F]

I've got a few pairs of speakers I need to replace the foam surround on. I have
found a bunch of places with widely different prices. Does anyone here have
experience with these or others. I am curious about the quality/durability of
their products. Are the expensive ones worth the price difference?
