Recommendations for digital pianos

[akjhshg2]

Hallo,

I need to buy a new digital piano, my old one was a Kawai ES3 (weight: 19 kilograms - 41 pounds) and now I would like to have something better in sound quality and something lighter.
In general here are some features I need:

• Full Graded Hammer Keyboard
• Different high quality piano sounds
• USB midi and LINE OUT jack connectors to connect the piano to amplifiers
• Weight < 15 kilograms (33 pounds)
• Maybe also the possibility to mix sounds (e.g. piano and strings)
• Price < $745

I went to a store and they suggested the following models:

• Casio Privia PX-A100 (anniversary edition) - price: $721
• Kurzweil MPS10F  - price: $882
• Orla Stage Talent  - price: $596

I like Casio PX-A100 but I'm not sure those models are the best I could find below that price (I excluded the Kurzweil because I don't like the sound and the weight is 18 kilograms (39 pounds).

So do you have any advice about a model to buy?
I'm used to play at home and especially to make concerts, besides I have been playing piano for 11 years and I since I started to play graded hammer keyboards I have always played Kawai ES3 so I'm not an expert about models and other features etc...

Thanks
