can i give you some advice retal ? Please dont go selling the psr3000 just to buy the RD700. From wht you have said you are a beginer player. I know lots of people who have spent thousands on a top of the range digital piano thinking that somehow the instrment would bless their hands and make them virtuosos only to find 6 months later that it has now become the most expensive book shelf they ever purchased !!!!!

There is far more you can do with the psr3000 than you could ever do with the RD700 in terms of musicality, creativity and sheer inspiration to learn and develope your music skills. But arranger playing is a slightly different discipline to straight piano playing. Thats not to say you cant use it simply for piano playing but you might find hat you have some limitations on straight piano pieces especially classical pieces written for a piano with the full 88 note range.

If you really hate the psr 3000 then by all means sell it but then purchase a deidicated digital piano. Go for an intermediate model. Others here will sugest some to you i am sure.

Until you have actually shown at least a couple of years dedication to learning to play piano, you SHOULD NOT EVEN BE CONSIDERING A TOP END DIGITAL PIANO.

Unless of course you are short of book shelf space.......
