I think she's referring to the XC 3401.
The picture is NOT a Griot's:

Doesn't look like a Megs unit, either:
When I got mine the other day, I put some white grease on the gears, sprayed the felt ring with Silicone spray and put a lock washer (8mm) on the bolt. I'm pretty sure I won't have issues, but will report if I do - it should be getting a pretty strong workout!
