I've always been a ketron sound module guy (A2000, MS40, (2) X-4's,SD3) but their pricing is now a bit high...I'm getting a lot from my Korg now.

I think familiarity with the navigation keeps some with the same brand. I showed a friend mine but he was immediately stumped with Korg's operation and will not part from Yamaha.

Of course I'd want to know when Russ's SD5 goes on the block...
