Yeah.. I remember wandering into the music store five years ago and messing with it. I thought it was the greatest thing in the world. Like ED said, It is going to be psysically slower hardware-wise as VA has come quite aways since then. So if you find one cheap enough, (around 100 bucks)I suppose it's worth it. After all, it just says oberheim on it, but it's not an oberheim, so don't pay for a name.
My Matrix 6 and Xpander aren't really oberheims either, but nonetheless, still useful. Heck the OB-12 couldn't possibly sound any worse than the Korg Z1. That box is alias-maximus.
