CME Xkey 25 by Chigger
Five stars all the way (except for sound quality) for the Xkey 25. It's not loaded with features at all but what it does have works as you'd expect. It has a surprisingly good feel to the keys, easily playable, though admittedly I am not a keyboardist. I'm using it for triggering samples and simple parts and fills with various VSTis. Small, easily portable USB connectivity/powered. It serves it's purpose well for what I use it for.
