Looking at the feature list on the New Hammond Sk1, I was very please to see they have included a TRANSPOSE button...for us singers this is a godsend...Bravo Hammond & at 15 lbs? cant wait to try one.
I also wonder what Piano sample they have in the SK1..sounds wonderful? 
 Yep, that is a very good piano.
 What way would you use the SK1, Donny?
 With a module, or as an addition to your PSR-S910, although I can't see the latter as you do so many gigs per day, that anything extra would just be in the way?
 I really like the 
SA JazzRotary, and
 SA RockRotary on the PSR-S910...actually, they are 
samples of a Hammond...would you need that much
 variety in organ sounds to warrant an SK1?
