Wiardgroup

I want to start with a analog modular, so far with my research, 
Wiard is the one I like the most, compact just 8 awesome 
modules, but I can affort 1 module every one or two months so is 
it worth to start on the 300 series? I want to end with at least with 
the complete line-up of the 300 series,  and is it just temporary 
that some version 2.0 faceplates are sold out?
