The price I got it for was excellent, ask Domenico for a quote if you are interested in one. It is cheaper than a Wersi Ikarus by loads. Not sure of Tyros 2 and G70 but certainly it's competitive and worth every penny. You don't have to go for the all singing model as I did, there is one cheaper.
The weight is not much more than my SD1 or G1000, it's manageable.

Turning it on for first time now so will update on sounds, styles, features soon.
