I ordered one 2 days ago for my 70 gallon cube which isn't up and running yet, no converter needed, it's all set to plug in and go, I ordered the BM100, cost me 160 canadian including shipping (USPS), what the hell, if the pump dies in a year, it's 40 bucks for a new one, there suppose to be very well made.
I ordered it from here.
