Just use Google for Powerhouse Amuse importers in the US.
J's Racing is imported by AJ Racing - they've a couple of threads running here regarding T1R products, which I think is their own designs made in China.
I'm sure they could also organise an Amuse if you were so inclined.

Look for Euro-R or CL7 - that's it.
