I can't really say I'm a Roland fan, but I know I'm not familiar with Kawais. I do have a Yamaha CLP-930, but it's pretty much gone by now. I believe Yamaha improved their key action after models such as mine, so hopefully you wouldn't have that problem (but CLP-220 might). But as it is now, after about two years, I've worn it down until about a dozen white keys broken, my sustain pedal is almost shot (really need to squeeze it down), and my LED display makes loud buzzing noises constantly (I don't know why). Some keys stick horribly and some stay down and don't come back up after being pressed. This makes me so mad because now I can only play pieces in Db and Gb major.
Now mind you, I did get it used, and I got it for under $2,000 USD, so it may be a couple years older than that. I would recommend going to your local retailer, though, and seeing what they have that's used, you can get a much better model for a lot less money... just be careful you don't get one that's been through some use like I did, mine was probably on the verge of having the first thing go wrong with it when I got it, so when I did get it, one thing after another would periodically fail.
Other than that (and that I believe the action is improved and more reliable in newer models), I would say Yamaha is a great direction. The touch seems phenomenally close if you're not a serious pianist and haven't been playing for like eight years.

The only thing is, if you're getting serious, it won't cut it, you'll need a real piano, you can't replace a real piano. I thought the action was so close to a real piano, for how much the Clavinova felt real to me, once I went to play a recital after a month or so on a real piano I had a hard time because I had gotten so used to the 'fake' action. It was unbelievable, you don't realise how different it really is, but it's just a little, just enough.
If you're not playing any particularly difficult pieces in the near future though, I think a Yamaha would keep you plenty happy. The sound is nice too, some newer models even let you tweak the tone between soft and bright and have many different piano sounds to choose from, so you can choose one that suits you.
