Resin Bonded Diamond Wheels?

[darita]

I'm wondering if anyone has had experience with and a source for resin bonded diamond or CBN wheels for T8?  I've used them with great success with other sharpening systems and would like to try them with my T8.

I haven't tried them, but I believe Schleif Junkies sells them.

Also, there are resin-bonded CBN wheels available on Amazon. 

In both cases I think they're only available in high grits.  For example, the Amazon wheels are available in 2500, 5000, and 10,000 grit.

I've been seriously eyeing the 5k CBN wheel myself, but at $600, they don't come cheap.
