my son does keyboard lessons, has been told needs weighted to progress.....so its to improve technique.....but his freind also has a band and they want him to join (unfortunately its folk? wtf?)

but anyway....good piano and organ sounds needed.....good (technique improvement) action needed.....nice to have other stuff but not as important.

Have been thinking of yamaha 'dgx' 'cp' and 'p' ranges.....have been told np30's are a bit rubbish.......dunno anything about casios or rolands ....oh and i want it cheap
