The Kurzweil Micropiano is a permanent part of my gear and if you can find one then I would recommend it. It has many useful sounds and the acoustic piano is warm and pretty much spot-on. There have been times that I would be stuck playing someone's digital piano so I would always take the Micropiano with me and usually wound up using it. I can't compare the Micropiano to the Nanopiano but the legendary Kurzweil piano sound will always be a personal fav.
