The CLP series pianos act as pianos (with some extra voices available).
The CVP series pianos add many accompaniment features. They are basically the same as the CLP-series in their piano functionality, but the accompaniment features raise the price MUCH higher.
The CVP-x01 models are not nearly as good as the CLP-series (inferior keyboards). You need to bump up to a CVP-x03 or -x05 to get a good keyboard. But you'll pay A LOT for it.
Yes, the Roland HP-series is known for noisy keyboard action. Judge them for yourself.
Roland, Kawai, and Yamaha have slab keyboard models that might suit you. They're much less expensive, but some of them have keyboard actions that are nearly as good as the expensive consoles. You need to decide whether you want the console appearance (and stability) or not.
