Roland, FP10, FP30X, my own choice would be a FP E50 which does have more features and again growth potential, but imo it does the best keybed action in sub $1000 DP’s
That reads like the DP-E50 has a better action than those other two, but from the specs, it looks like all three have the same action.
I’m looking for a basic, no frills, no added instruments, sound effects, synthesizers etc. I’ve been researching and just looking at some of the keyboards is overwhelming with all the added features.
While Dave's suggestion of that used PX5S is a good value, it doesn't meet that criteria of no frills (or let's say, as few as possible, since it's basically impossible to find something with none). He may have been assuming that you wanted no frills because you didn't want to pay more for things you didn't care about, so that looked appealing as a way to get lots of other stuff without really paying more for it, but you may prefer no frills for other reasons, and that board's got a ton of them. Plus as Biggles said, you likely want something with speakers, and that board doesn't have them. That's important because, without built-in speakers, she'll be limited to using headphones, or you'd have to also buy an amp for it, which is additional expense and clutter, and something else she'd have to turn on and off separately every time she used it. Plus the low-cost amps generally provide an inferior playing experience compared to built-in speakers.
I pretty much agree with Biggles' post, except that again the FP-E40 and PX360 have plenty of frills. I'll also mention another in the Casio line, the PX-S1100, which is another nearly no-frills model, and has upgraded piano sound and feel compared to the CDP-S360. Also, he mentioned Korg but did not give you a model number, the model of theirs to look at would be the B2. Korg doesn't seem to get recommended as often as Yamaha/Roland/Casio/Kawai, but I wouldn't overlook that one in your comparisons.
Lastly, you'll need something to put it on, so factor some kind of stand into your purchase as well. There are generic stands, but also, most if not all of these models have aesthetically pleasing matching stands available, which may be preferable, especially if this is going in a living room, for example. Sometimes those stands include pedals units, which are neater, stay in place, and can be more faithful to a "real" piano experience in feel/functionality. Sometimes pedal units are included with the stand, sometimes it's a separate purchase from the stand, sometimes it's not available. The Korg is a little different from the others because instead of having those things available as separate purchases, they sell an alternate model (B2SP) which is the piano with those things included.
