I own a P250 (as well as a GranTouch 1 and a Clavinova). The P120man (aka p120dUdE) can find no flaws whatsoever with the P120. He is probably a teenager and I know for a fact (his own admission) that he has never made one cent in music. He has been banished from at least one forum http://www.musicplayer.com/cgi-bin/ultimatebb.cgi?ubb=forum;f=18
and has also found himself in disagreement with Mike Martin - a top Yamaha guy in the US who also posts at the aforementioned forum. My point? Take his advice with a grain of salt.
I have played many hours on my P250, directly and also via my GranTouch midied up to it. The sound is not 'rough' and the interface between the keyboard and the actual sound leaves nothing IMO to be desired. I did find that I had to add reverb to almost all of the default settings. In this instance, the Roland RD700 has a better idea - a reverb knob that works globally. The electric piano sounds (Rhodes) are superior in the P250 compared to the P120. I have spent about 20 minutes playing the P120 and when it was introduced it probably was one of the best keyboards. It seems to have been marketed as a home piano and not a professional stage piano (my opinion).
Having said that, the P250 has an _excellent_ piano sample - possibly the best in a stage piano. (I read somewhere - I don't remember where, that the P250 has 22 megs dedicated to the GrandPiano 1 voice ... don't quote me on that.)
At any rate, I am a professional pianist (for what that's worth) and the P250 is worth the price. If you are looking for a piano for home use (student, a second keyboard to own), the P120 would be fine.
I do _not_ know for a fact that the action of both keyboards is the same. I have opened my P250 to take a look around ... and also tightened up just about every screw that was _not_ holding down a printed circuit. To open up the P250, crawl underneath and remove six or seven of the larger screws you see around the edge. (I opened up my P250 two or three times - it's a piece of cake to open. The lid will need to rest against a wall as it is hinged and I wouldn't trust the tension on the wires from the main board to the printed circuit boards on the lid in a 180 degree opening.)
The P250 has a 16 track sequencer and the P120 has two (I believe). The sequencer is not perfect - I've found one flaw in the OS and passed it on to Yamaha. The sequencer would be easier to work with using your computer instead of going through the P250 interface. I use the sequencer for just creating bass and drum lines to practice in a 'trio' setting. I simply play a bass line against a high hat on two and four.
If you have more questions you might find more action (no pun) in the forum I mentioned.
