Anyone Use A Shuttle Pro Device For Lightroom Yet?

I've seen some reviews on these (http://retail.contourdesign.com/?/products/23) and they look pretty cool. 
I've tried out a few #Lightroom  devices but I haven't settled on one yet. I kinda like the keyboard from Motibodo but it's a little pricey. Figured I'd see if anyone has a favorite.
