I have had mine for a few weeks, I love it! I'm coming from a 7 year old flagship mini dv cam.
I first bought the panasonic 720 which I returned right away, the picture was washed out and the image stabilization was nauseating
The Sony 430 has a great menu layout , great picture which I view on my 110 " diagonal screen through my 3 chip dlp pj and the optical image stab is amazing! This alone makes it worth it. this model is the first cam under 1 k to have optical stabilization.
Other than spending 1700 on the canon hg30 the Sony 430 offers a lot
