Aaron, I use all Kino. I have some 4x4 banks and also some parabeams but if I had to do it all over again I would just get all Diva 400s because they are low weight, dimable, and pack more punch than the banks.
Here is a good cheaper alternative

But I use Kino because in 3 years of shooting they have NEVER FAILED ME and that is worth the extra dough in my book.
