I got mine from Sam Ash online with stand for $6k with free shipping and no tax. I already have a bench.

I run it through my studio monitors: a 2,000 watt mono block electrostatic setup with a 1,000 watt servo sub woofer. (I have owned a recording studio for over 30+ years)*

I did a shootout with all the sampled piano setups I have (about 400 Gig total) and the Roland won. The sampled pianos, while good, just sounded static in comparison. They didn't breathe. Also no drain on your CPU, and the ability to change pianos almost instantly to find just the right piano for the track.

If you are auditioning it in a music store be sure to check the velocity setting. You can adjust it from ultra light to heavy and it will affect how the piano responds.

* I've also done many location recordings of grand pianos in a variety of churches, clubs, and auditoriums.

The proper comparison of the Roland is with a miked piano. Otherwise it's apples and oranges.

Even with a baby grand or larger in good shape you still need a big enough room for it. A grand piano was meant to fill an auditorium, a space usually bigger than an average house. I tend to cringe at the sound of most "real" pianos I encounter in someone's living room. The room resonance is usually too high and the T60 decay rate way too fast.

If you record a piano, however good, you are now faced with: room acoustics, microphone selection, microphone pickup pattern, microphone placement, number of microphones, mike preamp selection (tube? solid state? transformer?), and choice of A/D converters (if a digital recording).
And the sound will end up coming out of speakers.

In a live situation, where a piano is amplified, the Roland could very well end up sounding "better" than a "real" piano. (Given the typical sound reinforcement setups I've seen)

I tried the V piano at Guitar Center in Nashville. They had it in the front of their synth room. My first impression is that they had it playing through a very high quality monitor system with a sub woofer. As I played I felt the sub was too loud and the piano sounded much too bass heavy. After I had been playing it for awhile a man came up to me and commented on how beautiful the sound was. At this point I asked him if he wanted to play it. He sat down and I moved back from the speakers. To my surprise the sound was much, much, much, much better after I stepped back from the piano a few yards. It turns out that Guitar Center didn't have an ideal speaker placement for their demo unit. I was impressed with the expressiveness of the piano. IMHO It is kind of a plain Jane. For that much money I would have expected an impressive aesthetic design but it's not a real looker. It doesn't look all that bad, but it's certainly not going into the Guggenheim anytime soon. I will say that after that I went to the back of the room and played the Yamaha flagship stage piano (not sure of the model number, but it's the high end stage digital piano) and it sounded like a wheezing chicken compared to the V with the high end monitor system hooked up to it.
