I'm not too fond of the sound and the looks. The looks shouldn't be important off course, but hey....
It's hard to explain in words what I do not like about the MKII's soundwise, most of the time they're too clean and sweet for my taste. When I hear a MkI, I hear the wood and the dust through the tone, more edgy, more body and definition and that's something I like personally. It's all about taste you know, but I prefer a mid/early 70's MkI sound over a 80's MkII sound. Maybe it has something to do with different pickups or tines or maybe it's only psychological, I don't know. If I were you I'd try to listen to as much Rhodes piano's as possible and find out which sound you like best. Things like heavy action or other shortcomings are relatively easy fixable, so don't judge a vintage on it's action only for instance. It's all about the sound in the end.....
