I guess not! 😃 I wonder if they have more of a following among the non-classical crowd. I've seen Mickey Finn play with Samantha Fish a couple of times in the last year or so and he had (among other things) a Korg (the SP-280, I think).
I'd be curious to try either of these brands but I've never seen on in a store anywhere near me. Maybe next time I get to "the big city" ...
