I'm using a Token Ninja in my Speed Concept.
No problems with it yet (only fitted at the end of last season, and just kicked in racing for this year).
Fits solidly, and if anything has stiffened up the feel to the bb area.

Like you found the bb's are available but fitting tools are harder to find, and you do need it.
I bought them as a pair off ebay via a shop in Taiwan (cycling boss)
