For those who consider it in their purchase decisions, I posted previously on weight difference in sd7 (33lbs) vs sd60 (41.8lbs). Just got a note from AJ about error in specs. Sd60 is 35.2 lbs..that makes more sense. Original thread below..

Weighty Question

Sparky,
Seems like most of the "go to" keyboards have gotten heavier than most of the senior age
players want to or can haul around to gigs. What I have done is purchase the Ketron SD40 module and a 49 key M-Audio controller- total weight for the two is about 16 pounds! Great sound and easy to move around. I sold my Ketron SD7 keyboards to make the change.

I use the same with my Hammond SK1 or M-Audio 61. I fully agree.
