Chocolate Grating

Sorry, I posted this question on another thread.

Here goes again...

Does anyone have an automated way to shave chocolate into fine particles (like you'd get from a cheese grater) that works well (not a lot of melted goo)? The chocolate flaking/shaving machines appear to do larger curls, and are fairly expensive. Has anyone tried using an electric cheese grater, snow cone machine, etc. with any good results?
