I never had a keyboard that wasn't great and fulfilled my needs at the time it was purchased. They all performed admirably. And, the only reason I got rid of any of them was because after a year or so of usage I found one that either sounded better, or the OS was easier to work with. Upgrades are always fun--some are just more fun that others.
Cheers,
Gary
