I have decided on buying a Yamaha YPT310. It has everything a beginner needs, and is affordable at the same time. 61 Touch Sensitive keys, 32 voices, a lot of instruments and styles, MIDI capabilities. So I will be able to learn how to play, and at the same time will be able to connect it to my laptop through a built-in MIDI in/out interface. So the keyboard + MIDI-to-USB adapter and I am good to go :) Okay rest of me, time to earn some money!
