I found that there are no good looking Grand Pianos with a full interior out there for Blender, so I decided to build my own Version. I came up with this non-Brand, full rigged Grand Piano which suites fine for architectural visualisation project. If you are interested in, have a look at my portfolio at Blendermarket.com.
The Grand Piano sells for $15 on the Blender Market.
