The 76-key is almost 10 lbs lighter than my Pa1xPro. Hmmm, I feel those itchy fingers comin' on.

Same here. Problem is, I haven't turned on my PA1x Pro in about a year.....which is my main problem with Arrangers, after awhile heavy-duty boredom sits in. By contrast, after 50 yrs. I still get a buzz every time I sit down to a B3. On the other hand, I'm still a gadget freak and there's nothing better than a MUSICAL gadget, especially one that sounds good (for the first three months anyway

). We'll see.
