John,
If I were in the market for a piano/do all keyboard, I would definitely look at the Yamaha Clavinova line. Yes, they tend to be heavier, up to 200 pounds or more, so it's not something you're going to throw in the back of the car. On the other hand, the feel and playability of a Clavinova is the same as the Yamaha Grand Pianos. It just FEELS right, it doesn't bounce around on a stand, and it's solid. You can really dig into the keys, and not worry about it falling over or breaking.

There are two lines, the CLP and the CVP. The CVP is what I like, because it's an overgrown Arranger Keyboard, and the sounds are just awesome. Furthermore, the newest ones, like the CVP 409, are now coming with MegaVoices and Super Articulation, just like the Tyros 3.

They are expensive, expect to pay $5,000US or higher for a top end model, but it's something you'll keep for a long time, and your wife will love it.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
