Hi Stephen,
As you know, my T3 will be delivered today. I am not one to jump up and down with unnecessary excitment so I will hold off my opinion until I feel comfortable enough to take it on my first gig. About the 76 key thing - I would enjoy turning off all the "gadgets" and just playing piano once in a while. Unfortunately, being nearly 70 years old I have to be careful about weight of my keyboards. I had to sell my Korg PA1X because it was just to heavy for me to handle. My feeling about all of this is simple - if you really use your keyboard much like you would play a piano than the 76 keys would be really nice. On the other hand if you are an "arranger" type player than I doubt it really makes that much difference. I still own a piano and an organ but seldom play either anymore. I will provide a true and accurate "review" of my new T3 but not until I have time to give it a good workout and feel like I know what I am saying.
Best of luck with your decision.
Hammer
