$29 if you get them from Alltech, $24.95 if you go to WDC.  Only thing
is, WDC requires a check, Alltech accepts credit cards.

WDC is Western Design Center; they have a web page you can find if you
go through yahoo or another search engine.

The chip is only rated at 14 MHz, so if you want it to go faster, install
a fan pointing directly at the chip for cooling purposes.

Consult the FAQ, I believe this is it.  Also, to really help the speed boost,
you might want to consider boosting the cache.  I know on the Zip, you also
have to replace a 74F00 with a 74HC00 if you want to go faster than about
10 MHz.
