I personally think that quality of sounds is more important than quantity of sounds. I also think the LE sounds are better than the XP-30 sounds. I think having a built in sequencer is better than not having one. I think the Korg "system" is easier to learn and understand than the Roland "system". I think a Triton TS is better than any other keyboard presently being made and would tend to buy the LE as a starter to move up eventually to a TS. But these are just my personal opinions. I have a fully expanded Korg Trinity V3, a Korg Pa80, an Akai S3000XL, a Korg D1600 and a Compaq 17XL460 laptop in my home studio and am very happy with the way it all works.
