Can anyone comment on the keys? I had a psr 530, 630 , & then 640 and then a yamaha ex-5.
I hated the psr series for two things - i get bored hearing the same sounds and secondly, the keys are flimpsy and also not full size/ semi-weighted. I have always loved to tweak sounds and so moved to ex-5 which is an amazing keyboard w.r.t sounds and also the feel of the keys were awesome. but, i badly missed the accompaniment feature and it had a lot of bugs (yamaha's keyboard are well known for bugs, i guess).

Now, i decided to get an accompaniment keyboard and buy a synth module for more sounds. does any of the arranger keyboards have semi-weighted keys? or am i better off buying a arranger module and a synth keyboard/controller ?
