Best Piano Instrument <- recommendations please!

If you have kontakt there's a great new product called *the definitive piano collection* which goes for $199 by native instruments.  Its four different pianos, all of which sound great.  Its pretty hungry in resources I've noticed, at least a couple of the instruments are.  Its a more versatile (and cheaper) alternative than buying those single instrument versions.

I have been very happy with Addictive Keys. Affordable and very easy to operate with lots of control. Not the best out there but for the bang for the buck, it's pretty hard to beat!

Something for everyone: http://www.sampletekk.com/

Don't forget Orange Tree Samples Evolution Rosewood Grand, a love emulation of the Yamaha C7.
Also, 8DIO has some nice pianos, I have the 1969 steinway D, which is also nice. I also use Pianoteq--the full version is more tweakable than the Player version, and the Pro version is fully editable, note by note. I have the full and I don't think it's "small" but it is a physical model rather than using recorded samples. Still quite realistic and customizable in many ways with a number of models, from Steinway, to Bluthner, to their hybrid K2, all of them very nice.
there are others, but I don't have them (yet).

Not yet released, but I have high hopes for Wavesfactory's Mercury Piano... ;) Other than that I'd say the NI Definitive Piano Collection is pretty darn good: https://www.native-instruments.com/en/products/komplete/keys/definitive-piano-collection/
 
If I wasn't waiting for the Wavesfactory piano then I'd probably grab this: http://8dio.com/instrument-category/piano/#instrument/1928-steinway/
 
I have a soft spot for playing a piano, well, piano. :)

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. 

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...

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

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.

Hey, that's an unidentifiable flying object!

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

If anyone doesn't like this fred, they can kiss my Fazioli. 

They are old, but the Sampletekk Bosendorfers' sound big and inspiring to me. Of course if you want a BIG upright, check out The Giant from NI.
 
You can look at the Piano in 162 and the Estate Grand Limited as two freebies with a very good sound, imo.

A bit cold to me, that Hammersmith. But I do love ImpactSoundworks' Pearl concert grand.

Gotta be BassGranddaddy to always end up with the Flintstones.

I think the NI definitive Piano Collection are the same sample sets of the Classic Piano's from way back. It has a Bosendorfer, Yamaha C7, Steinway, and an Upright of some flavor. Somewhat uninspiring to my ears after all this time - but they aren't bad. I picked them up years back for about 100.00 on a closeout before they ported them to Kontakt.
