Do not go with the Yamaha, in my opinion Yamaha digitals have the worst piano sound and action and is like a toy compared to the digitals from other brands.(Casio, Kawai, Roland) [/b]
What an odd comment.
I own a Yamaha P70 and a Casio PX-700. I got two because I had two separate places where I wanted to be able to practice via headphones. (I also have a Casio CPD-100, but that is hardly in the same league -- it has nice action but sounds awful.)
I like the Yamaha quite a bit. It has a nice sound and the action/feel is pretty darn good. The Casio is arguably better on both points. The Casio actions are very well done for a low-end digital. Nonetheless, I can see some people thinking they are too "stiff" (and I've played some nice acoustics that were "easier" to play than the Casio). Those people might prefer the Yamaha, which is a little lighter to the touch, I think.
On the sound, they are just different. The Yamaha has a slightly mellower tone, I think. (I don't have them in the same place to compare side by side, but that's my impression.) The Casio benefits from a cabinet, though, where the P70 is more like a stage piano setup, with small speakers on the top. So the Casio would have an "unfair advantage" in a direct tone comparison. Still, I like the Yamaha quite a lot, even with the stock setup.
Both are very decent keyboards. I realize we are talking here about different models, but the yare not that different, and the above comment was more generalized.
