Speaking of Roland I have noticed a lot more Roland gear being sold on ebay as opposed too Korg. But Yamaha has the highest grouping mainly do to all those home keyboards.

Seems to me it's Yamaha, Roland, Korg, and then everything else. Well on Ebay anyway.

I always wonder why Roland, Korg and Yamaha still dominate the market. While the ones from Germany and Swedeen are trying to make a name for themselves. Espically here in the US.
