Thanks Larry! Here's one comparison:

Akoustic Pian:

Ivory:

Although I think "Ivory" sounds a little bit better (especially in the high register), don't know if it's worth the extra money (not to mention the extra expense of the ILoc).

I sent these links to two friends. Both liked the Akoustic better. I imagine it depends on the playback systems. Anyway, they're both good to my ears. Yeah, Ivory slightly better. I still have the rest of the day to decide, but I want to get past this - it's making me crazy.

I also decided on these samples:
