Hi there. Not only am I new to this forum but I also don't play piano My 8 year daughter has been learning to play on a hand me down keyboard which she has now outgrown. I want to buy her a reasonable electric piano or keyboard but with her being 8 and all, I don't want to spend a fortune on something that may well end up gathering dust in 12 months time. Her teacher has recommended looking for 88 "weighted" keys (I now understand there is "weighted" and there is "weighted"). I would like something that can be used as a Midi controller for my DAW, so either MIDI or (preferably) usb is a must. Whilst keyboard action/feel and basic sound quality are my main concerns anything that keeps her interested at her age is a bonus. So being able to play different sounds, additional learning tools etc would be a bonus rather than essential. My budget is around AU$600-700. I've done plenty of research and have narrowed my options down based on price, value and availability to a couple of Casio's but can't decide between the 2. These are the CDP-220/230 and the PX-150, both of which I can pickup for a little over AU$600. The main differences I can see are that the PX-150 has greater polyphony 128 rather than 48 (will this matter to a beginner/intermediate player?). The sound engine is different, although the CDP gets good reviews soundwise. What I can see I am getting with the CDP over the PX is the additional sounds (700), lesson features, sampling (of little use I imagine but fun for an 8 year old!). I would really appreciate any thoughts from folk more experienced than me that might help me decide between the 2. Many thanks in anticipation, please keep your answers non technical so that a simple guitarist can understand
