Compatible Keyboard for SoftMozart?

Hi,

I'm thinking of buying a SoftMozart-compatible keyboard in the near future. It is for my 2 year old daughter. I'm still gauging her interest in music, so I'm not very keen on putting too much money on high-end keyboard. My plan is to get her some decent keyboard that can last her through 2nd or 3rd grade. I'm thinking of putting her on SoftMozart lesson between now or 12 month later.

I looked at the manual that SoftMozart allows USB-to-USB or USB-to-MIDI connection. So, here's my question: Of the following keyboards, which are compatible with SoftMozart and which are "better"? I have no experience at all in musical keyboards. I'm thinking of those in $100-250 price range.

Yamaha YPT-230 .

Casio CTK-4200 .

Yamaha YPG-235 .

Yamaha EZ-220 .

Yamaha PSR-E433 .

Casio WK-225 .

Or any suggestions?

I finally settled with Yamaha YPG-235 and it is compatible with Soft Mozart. Make sure you install the drivers provided by the manufacturer.
