Nick, the only 115V ELBERG MP-8 ever made was made for me, and is probably the only one in the US. If you have some questions about the MP-8 you can contact me.
Looks like if one could be had it'd only cost something like $479 USD a channel. That doesn't sound like "super high end" but I guess the exchange rate has some part to play. I too never heard of it before but I live in the US. It looks cool anyway.
