SB400 and D7000
I am set up exactly like that ( D7000/SB400/Stofen Omnibounce ) and I really like the overall performance, but especially the weight and size, I am sure the SB700 would be nicer, performance wise, but it's just too big for me.
You should be very happy when you receive it.
As far as a replacement, there is none I am aware of at this time.
