My gear was actually closer to the USA than I was, so I caught up with it. 
I have 3X Quadratt, headphone amp, and line tiles in installed in my single row current rig. All are great. I also own the noise tools tile (pretty good for my uses, but I wish the clock had more range), reverb tank tile (good and fun Beltronics tank design), stereo I/O (excellent!), and USB power (very handy for dark gigs, as noted above) tiles. For my uses the Quadratt is the star of the show.
