With your taste for heavier actions, you might probably dislike the ultra light EA/7 keybed... Play before you buy.. for the rest, where it comes to features, the ea/7 could have been the PA4x little brother.

The SD7 is indeed much more expensive, but it would get you the best styles in the buiseness... no ones bared.. but for a gigging player its also a bit heavier then the Roland... tough also much more durable build. Also the SD7 dus have a build in harmoniser, which the EA7 lacks

In the end both in build in sound quallity the SD7 is a huge step up from the EA7.. almost competing with the T5 and PA4x, where the EA/7 is in the range of the Korg PA600 CAsio MX 500 and YAmaha S770... Which it indeed beats for vallue for the money


If you are looking for a cheap light arranger and dont mind the key action, i would go for it... then it adds something...



However, since you have both a S970 and PA4x, i dont see a role in your collection for the SD7.... but since you prefer often 88 keys... you could add an SD40 (the module version of the SD7) to any 88 key like the Roland RD2000(no aftertouch) Yamaha MOXF (same action as your GDX660) or Montage, Korg Kronos, Nord Stage.......... or Casio PX5s... and have best of both worlds, Great keyaction, good piano sounds, ultra light setup, and the best styles in the world... for the same price as an SD7
