Ceramic bearings

[cardzilla]

Does anyone have any experience using ceramic wheel bearings?  I have 3 wheel sets and I've noticed a big difference in drag between the three, I'm assuming from crappy stock tolerances. Feedback is appreciated and maybe where I can find them as well.  I've been looking for a while and I can only find MTB stuff.

I know Woodcraft (www.woodcraft-cfm.com) sells some, but not sure what brand they are

Thanks, Edgar, I'll check it out... gives me something to do in the off season so I don't go nuts.
