It's time for me to get a good solid grand piano in my rig. Electronic, of course. I have a Roland JV-2080 but the acoustic piano patches just aren't good enough. I'm thinking of upgrading to the XV-5080 with the Concert Grand card. How does that sound?

I've been using a pretty crappy grand piano sample on my ASR-10 for years, and I just can't take it anymore. I need something that sounds like a grand piano and is a good, clean sample. Any suggestions on what I should buy?
