I agree with Bill above (SemiLive) - If you tell us more of what you are looking for either in features or type/style of music then you would get more relevant responses.

If you like dance/Trance then I'd say Korg, if you want ease of use then I'd say Yamaha, If you want something that very few others have then I'd say Ketron, if you say quality piano then I would say Roland etc etc.

There are so many factors to consider from length and touch of keyboard and weight to the availability of third party or free styles.

As you are so new I'm sure you would be blown away by a mid range roland or Yamaha like the PSR3000 and it not such an expensive mistake if and when you change later on.

It may also be possible to buy one on sale or return and just pay a re-packaging fee if you don't keep it after the first month but you should be reasonably sure it's what you want before you do this.

I have bought "blind" the Tyros1 and 2 and also a Ketron XD3 and have not been disappointed but I have a lot of experience with arrangers having played and sold them for quite a while - you really should try to get to see some models to try even if it means a long trip.

Best of luch with whatever you get - you won't look back
