BTW, I looked at Dexibell, and it looks like they are fairly heavy in weight, which would eliminate them from the discussion, even though they look like very fine instruments. Maybe the 73 key one would weight less, so it's not totally out of the question, but they are newer and unknown so I may not be comfortable going in that direction.
And the weight is at the top of my list of priorities, which is the main reason I own the Casio PX5S and had hoped it would do "everything" I needed. So the list of items that matter are in this order of importance:
1. Light weight--I'm gigging a lot these days and I'm not willing to break my back or neck. I'm old. 30 lbs is my max
2. Great sounding pianos and organs--this is a definite must
3. Key touch/feel--fully weighted is still my preference if I have only one keyboard, but semi-weighted would be ok if it is full-sized and responsive--It's important, but not a deal breaker all by itself
4. No of keys--73 is the minimum amount--no more 61 note keyboards, just not good for a single keyboard solution.
5. Price--I will pay what I must for the right solution, but hope to keep it in the non-Nord atmosphere, unless I have to to get what I need.
6. Brand--Don't really care that much, other than the quality of sound, build, etc.
Can't think of anything else that really matters at all to me.
So the finalists at this point--which could change--are, in no particular order:
Roland VR730
Yamaha MODX8 (or 7, perhaps)
Nord Stage 3 compact or Stage 3 HP 76 (the one I tried that was dead and mushy keys)
Some new contender (Dexibell, Korg, Alesis, etc.)
Thanks for all the feedback, and keep it coming if you are so inclined.
