Lovely, functional and reliable board.
I bought the PX-3 to console myself when parting with the old upright piano in my house. Piano has been an integral part in keeping my head on straight during the stressful times of the year, and I knew I wouldn't last long without one.
I also greatly enjoy messing around with plugins, layers, pads, synthesizers and the like through MIDI. Basically, I wanted a keyboard with a true piano feel but the power to do even more hidden beneath the keys.
My experience with the PX-3 has been great. It's incredibly lightweight, the lack of built-in speakers was a great design choice. It sounds good, the keys both feel and respond good, and the board has a ton of features and customization that I haven't even brushed upon yet. You can make a ridiculous number of custom presets which are easily accessible with two button presses, a big bonus for the gigging keyboard player.
I think the traveling pianist, gigging musician and studio hermit will all find something to love in this great-sounding, lightweight powerhouse of a package. Remember, if you don't like the onboard piano sounds, there's a whole market of fantastic Steinway sample libraries to choose from that you can easily access through MIDI. What's most important is how the piano feels on your fingers, and this one feels very, very right.
