Dist Cap....

OK, so it may not make me much faster – but am thinking of picking up something like this:

… have not purchased a distro cap, except from Autozone or something for a tune up. What to bid? Anyone have experiences with such things?

If it is a $30 thing, that would be cool. If not, not worth it for me. Opinions appreciated!
