RCduck7,
If you have your heart still set on the super-v, I just checked on ebay and there is still one pair of coaxes available from the pro sound company that was selling a while back. type "bm12cx38" in the ebay search box. When I spoke with them, they seemed like they were very accommodating and reasonable folks to work with. Danny could still set you up with the rest of the parts, and I'm thinking it would be a lot easier for you to get the cabinets made up locally than to figure out shipping complete crated speakers across the pond.
Hope this might help!
