Nah, I got the grinder off ebay several years ago. The seller of was a restaurant supply place out of New York. I got the burrs on eBay, too. This seller has an espresso parts store on there, but I can't remember his handle off the top of my head.
Anyway, I swapped the burrs tonight... the original ones seem identical to the replacement ones. Even the machine marks look the same. I guess they'll be fine.
