My opinion.........if you are a 'piano' player and have grown accustomed to playing with the feel and resistance of an acoustic piano keyboard - an argument could be made that you should steer clear of all the arranger keyboards mentioned here so far. As is said often here - the piano sample comparisons are subjective and are also greatly dependant on the room and the quality of your amplification system.

Perhaps the biggest consideration for you should be how often you need to move it around. If its often - you will probably end up preferring to learn how to play and adjust to synth-action keys because the unit weight will be lower.

On the other hand - if you don't move it much - you could stick with regular keyboard action and get a slightly heavier unit. In that regards and depending on your taste in sounds - there is the KF90 by Roland and the SK88 by Generalmusic. Neither of them are on the cutting edge but the KF90 has wonderful sounds.

As to stand alone piano sounds - the Roland FP3 is great as is the Technics SX-P50 and the Yamaha - all of which have piano action. You could take one of those and use it as a controller with an arranger module from someone like Ketron - XD3. One of the problems in combining differening sound sources though is the overall compatibility of sounds - lots of that is the difference in effects processing - but not all products combine well just because of the types of sound generating and processing.
