Back in 2012 we bought a Casio digital piano. It was worth getting not just for the production of Grimhilda! during which it was used as the rehearsal piano, and later the piano in the pit, but also because I've kept it set up next to my computer, and use it in the winter time for singers and instrumentalists who come here for practices. It's warmer in the winter in this room than in the lounge where the grand piano lives.
I suppose the digital piano we bought is already out of date by several editions, though it's hard to know when these various instruments were produced (without doing a great deal of searching online). I think the Casio PX-130 is probably a later model, but who would know just by going by the numbering system. It's not easy to tell. This model looks more solid in terms of its structure - our one is basically a keyboard that sits on top of a trestle, and surprisingly isn't attached to the trestle in any way except by gravity. (Once it slipped when I was putting it on the trestle because the screw holding the trestle wasn't secure, and there was a moment when it looked as though the whole keyboard was going to dash itself in pieces on the floor. As it was one of the top notes caught on my hand and came loose, to my horror. However it turned out it was a matter of moments to fit it comfortably back where it belonged.)
The PX-130 also has a stand, but the the base and the keyboard fit together all of a piece. You can detach the keyboard part from the base, and apparently it's light enough to shift around. It weighs 25 lbs, being an American keyboard. My keyboard, even though it came in two parts, was quite heavy. I know this for a fact because I had to hump it out of the car and into the rehearsal rooms on innumerable occasions: there were about thirty steps involved in the process. (By steps I mean ones in a stairway, not steps you take.)
Reading about the PX-130 makes me think it's probably a better digital piano than the one I've got; certainly the advertising gives that impression. However I don't think there'll be any new pianos in this house in the near future. We have other things (not necessarily more important things) to spend our money on.
