I'd go with a XK setup. If you're gonna run a leslie with it...I'd go with the XK 1, 2, and 3. If you wont have a leslie....the XK 1, and 2 actually have "better" leslie simulators than than the XK3 IMO. But like someone said earlier, going with a XK setup/system you'd save a bunch of money and get 95% of almighty B3 sound!
