Yamaha PSR-E403
A little different type question is there a cheap one for a guy who will not do much buy?
I ultimately bought the
Yamaha PSR-E403, a relatively inexpensive model (about $200), and can recommend it.
It is a 61 full-key synthesizer with a USB MIDI interface and an amazingly large number of features. The keys are not weighted, but have something called "Touch Response." The main thing I wanted was the piano sound, which is one of the selling points for this model, but experimenting with the other features is fun.
I read numerous reviews of this keyboard before buying it, the vast number of which were very positive; many were glowing recommendations. The negative reviews were mostly along the lines of "this is not a keyboard for a serious musician; it is a beginner's keyboard." Since I am not a musician, and not likely to become one, and I am more or less a beginner (it has been many years since I played a piano), those negative comments did not discourage me from buying this model.
In case you are interested, the USB MIDI interface that comes with the keyboard worked with my iMac, but some of the software is for Windows only. I wondered about that before I bought this keyboard.
I decided against the M-Audio Keystation 61-ES mentioned above because, as observed in that post, I wanted to be able to play the keyboard without using my computer.
I hope this helps. Good luck!
