Hi Peter,

Having also had the opportunity to play one of these occasionally I agree with Mark. The XE1 is good at what Hammond do best. It can produce great traditional Hammond sounds. The physical drawbars provide for easy on the fly adjustments and the "waterfall" keys make for easy gliss movements.
The other instrumental sounds are well below the standard of many other recent keyboards including the KN7000 and the Tyros (IMHO). Similarly for styles.
It is heavy for a portable although not if you compare it with the original B3.
When combined with a decent amp and speakers I am more than happy with the organ sounds that can be produced on my KN7000.

Cheers
Len C.
