Statii.com
I've owned a few Statii but not a B2 so I can't really tell but I like this brand a lot, it's a very high end product and it's build like a tank.
Also Rob Green who builds them, is well known for his customer service and will help you anyway he can. He basically does everything on his own from the beginning to the end.
