For sale is a new set of SSP's Lab Sweet cast burrs in the silver knight coating. They might have a speck of coffee dust on them, but they are in unused condition, as I ended up deciding to use another SSP burr set. They are compatible with the Ceado e37s, however you will need some machine screws with smaller heads than stock for the upper stationary burr. These retail for $400, I'm willing to let them go for $350 shipped in the US.

Thanks,
Jacob
