FYI, edepa on the X board contacted Sal. He can't accomodate a group purchase right now. Told edepa to check back in a couple of months.
There are some extensive Zaino threads on the X board. Just do a search for Zaino over there. One or two are "stickies" in the detail forum (tips and tricks, primarily), and the others of interest to newbies would be the old group buy threads where there was discussion of what to buy.
