Isnt the Boss GT10B out of production ?

On closer inspection, it looks like it is. - perhaps we'll get a GT-100B soon?
The Zoom B3 is great too, but I find the switching a bit annoying live. The GT-10B allows for total control over any parameter.
As I said before, from what you say getting a few seperate fx will probably be your best bet. You could get a Zoom MS-60b as one if them. Plenty of amp sims, drives, modulation, pitch and other stuff in there.
