Hello! I've recently bought a Casio PX150 (from Thomann.de) I have a question about. Contrary to what I have read online (all excellent reviews) the key action on my piano is a bit odd: the keys feels kind of weak and have some lateral movement. Once firmly pressed and released the keys bounces and vibrate (kind of an exagerated key feedback) and they are very noisy as well. The sound and response is good, but the feel is... quite far from a real upright piano. The general state (aspect is OK - as new) and is functioning as expected. Is this how PX-150 keyboard is?! I am wondering since I have bought the PX-150 instead of the cheaper CDP-130 especially for the keyboard and key response, advertised as the one of the best from Casio. I haven't tested the PX-150 before but I had the opportunity to try the CDP-120 in a local store and the keys felt excellent, very firm and solid, much better than what I am experiencing now. Any opinion?Thank you very much!Cristian
