Hi Beaky...firstly, I'm sorry to hear of your wife's health problems...it must be very stressful dealing with it, especially with the way USA health care is set up.
I think you made a wise decision getting the PX-330...I've not heard any key wobble issues with that model, and I think the sound will be a big improvement overall.
Plus, it still is very light...and, it has real MIDI!!
Looking forward to your impressions.
Ian
Thanks for your best wishes too, Ian.
According to Casio, the key bed and several of the voices are the same on the PX-130. So the PX-130 is good for someone who wants piano and no other nonsense.
I wanted to ask Linda, if she's gotten beyond my health complaints, what other voices she likes on the PX-330 beyond the grand pianos. The PX-130 has two excellent grand pianos and two excellent electric pianos (and one bad one imo). The two organs (including a B3 type) and strings are great too, but I don't know how to play organ without accompaniment ... strings as well.
