P-515 B : I love it!

I am an adult beginner so wouldn't know much about other models to compare. However, I settled in with this machine and it feels and sounds great to me. I am nearly finished the first Alfred's book and look forward to many happy years from there. A comfortable stool helps a lot as well. I am just interested in the piano sounds so am not after an instrument that can play every sound in the book. Nice and simple. The Bluetooth for connecting audio helps a lot, especially if you use an app with an iPad or smart phone. It looks great with the companion stand at either side. I didn't go for the metal X style stand as those seem to restrict where you can place your feet.
