I like having the 76 with the low E and high G on my Yamaha Motif ES7.

In my opinion, 3 less keys doesn't save on weight that much and the saved length only adds up to 2 inches. I guess in the long run it may save them money in production. They don't save money by not having a solid white key as the bottom E. Doing 73 keys C to C (like Korg) or F to F (like Nord) you avoid having to stock the replacement part of a solid white key for the bottom... but you still need the top C or F so, what gives?!?

I use my Motif every weekend leading worship at my church. The reason I got the 76 key was to have more keys than a 61 but less weight than the HUGE Motif ES/XS/XF8 size and weight. It's been perfect for the last eight years. Do I miss the weighted... sure but when I am walking the 42 pound ES7 out of the church after our service 52 times per year, I know I made the right choice.
