I too have just returned from Caister, and I agree with Graham UK, at the price point you are looking at the Korg gives Excellent Performance, however if you are a Home Player with not a great deal of experience with keyboards, then Tyros 2 would probably be a better buy.
If you are prepared to spend more, then also have a look at the Wersi Ikarus with OAS 7 or the Liontracs Media station as these are software based, and have the added advantage of being able to play Giga Samples and use VST Plug ins, (Soft Synths, Emulation Programs etc) they also work out cheaper in the long run as you don’t need to change the instrument when something new comes out. (Major upgrades are mainly software based meaning you get a virtually new instrument for considerably less money then it would cost to trade in your old instrument for a new one)
