Singaporian (SING) dollars and australian (AUD) dollars.
Can't get rd-30's in aust that i know of unfortunatly, i asked iwaki aust and they don't do single unit orders, and declined to tell me of where i could get some

. Only IWAKI's that i can find on ebay are MD-40's, 15's & 10's (not the z's either). Bleh.
Also, the 20-PI is ~= md30rz, but is DC = more efficient

, though of course, real world gains would be negligable :/
