I'm also awaiting the release of the Wavesfactory's Mercury Piano. I want a Great sounding Fazioli SOooooo bad....

I must admit I was pretty impressed with the Alan Parson's Imperial Grand from IK Multimedia. The other libraries mentioned are all pretty good too, IMHO. I use the Addictive Keys one quite a lot -- it sounds decent, has lots of configurable elements, and doesn't seem to burden my system resources too much. 

Go try ProductionVoices Grand Gold as well. Some 114 gig uncompressed awesomeness.

And I second ImpactSoundworks Pearl as well as Sampletekk TVBO, Pianoteq Standard, OrangeTreeSamples Rosewood Grand, SoundIron Emotional piano and CineSamples Piano in Blue.

I really hope that Wavesfactory does good with the Fazoli but I have my doubts it will be that impressive. I don't know that they have the skill or knowledge on how to really do right by that instrument and make it something incredible. Most of their libraries have been very "meh". If someone with a better reputation was doing this, then I'd be all over it. For now...

Hey, that's an unidentifiable flying object!

+1 for Hammersmith Pro
 Also VI Labs Ravenscroft and Garritan CFX Concert Grand

I am intrigued by this library. Sounds very distinctive and is probably not a jack-of-all-trades sort of piano, but I do like what I hear in the demos:

I just purchased their Fazioli Complete package tonight but do not have it installed yet. Hoping it will work out and I won't have to upgrade to purchase the perfect samples also.

I have my faith in Jesus (sorry for the pun, the guy is really named Jesus) and that he will produce a great piano library. At least his plans sound very good (I write demos for Wavesfactory products).

I think you just identified it! Cool! And I was there.
