The 9000 pro is portable and I would venture a guess that it may be the only 76 key arranger that might fit your requirements and budget. It is no longer in production but is a recent model and can likely be found in your price range.

I am a synth player per se and am used to 76 and even 61 key models. I cannot say whether mot having an 88 key model would be a hindrance to you, but can tell you only that it does not affect my playing at all. I do not use or even prefer weighted keys, and I do not emulate piano sounds very often. If you are close enough to a music store, maybe she can try something out with 76 keys and see how it would affect her.


You might want to also pose this question over at the general arranger forum. I have experience with arrangers, but there are plenty of folks over there who know more about the different types than I do.

AJ
