Anyone using Infiniteresponse VAX-77 KB with X1 ?

Hey folks,
 
is anyone using the Infiniteresponse VAX-77 keyboard with X1 ?.

Wondering how easy to set up and how well it integrates with X1.
 
Also wondering about the pitch wheel/modulation slider layout - pitch wheel is on the left side, seems it could be a pain.
 
There's no agent for them here (New Zealand) so I'd have to get one sent direct from Texas.
 
I'd love to hear from anyone using one of these.
 
 
Cheers - Cliff
