PLUS is the price and the package
CON is you get what you pay for.

For the price they are both very good value, but I personally don't find them much of an improvement over the old RA90 or the equivalent E series. But if Roland had put too much R&D time into anything more than design and programming it would have cost three times the amount.

So if your after a new keyboard or module and are on a tight budget I think its probably the best you will get - and I would bet money that it sounds better amplified up than the equivalent Yamaha.

Personally though I would rather buy a second hand Korg PA series or Ketron SD5/SD3.
