Yamaha YDP-145 R Arius

The piano is easy to assemble (with a second person to assist you).
It looks beautiful and really classy, and you can start playing straight away; the set-up is really simple. The pedals are sturdy and the sound is very nice for a digital piano in this price range. I'm only just starting out but I'm sure it'll serve me well for years to come!

Only downside: The keys feel a little "plastic-ey"... I don't know how to describe this better... They are weighted, which of course is good, but they don't feel quite as nice and textured as those of an acoustic piano (or more expensive digital pianos, I suppose).
