I have the Roland Fantom X7 and I swear by it. I had the Korg Triton and I was not to impressed by the sound quality. I regretted selling Xp-80 for the Triton . When heard how realistic the X7's piano and the strings sounds were I had to get the X7. I use it as my main controller and write all my drum patterns with the pads. The X7's software editor and librarian through the computer's usb port is really a great addition. If you can not get the Fantom X the XA is the next choice.
