Hello, has anyone played the Korg SGProX, and if so, were you impressed with the sounds and/or action? I will be buying a controller in the near future, and have narrowed it down to PC88MX or SGProX. Concerning piano sound and keyboard action, has anyone compared the two? I've been searching and searching and searching the web for info on the SGProX, but, unlike many other keyboards, there is very little (which worries me), other than the same Mfg info and a few user comments which I keep seeing over and over. I would really appreciate some new input. Thanks for any info!
