Bernie, aren't the G70 drawbars good enough for you? Rather than invest in another keyboard or lug around a laptop, I feel the G70 drawbars are pretty damn good; so is the leslie sim. I owned a G70 and got rid of it for its weight and crappy vibrato/chorus section with the drawbars. But other than that, the G70 does drawbars excellently. As I said, the XK-1 is a killer organ, as good sounding as any XK-3 or C1. If you're just buying a board to have a new board, well that's your business. But a G70 should give you all the B3 sounds you want without having to add to you rig or subtract from your pocketbook. Good luck.
