The Rhodes Mark II Stage 73 is an electric piano designed for portability, hence the name. I don't think that you'll find too many people lugging these around to gigs anymore, but it's still an awesome electric piano for use in the studio or otherwise. There's not all that much that sets this particular model apart from the other Rhodes Stage pianos, but it's of the same quality as almost any of them in my opinion. These were made in the late 1970's and early 1980's, but as far as I know it's pretty similar to the Mark I. Of course this model has 73 keys and stands on it's own legs, although it's still quite heavy and isn't as easy to bring around as the 'Stage' name would imply. It's got built in vibrato and volume control as you'll get with most of the Rhodes, but beyond that there isn't much control and to be honest you really don't need much as this thing sounds great off the bat. I'm in love with the sound of a Rhodes in general, and this is definitely a bona fide Rhodes. To me it's one of my favorite keyboard sounds, if not my favorite. I don't know that I'd recommend the Mark II Stage 73 over any of the Mark I's or the Mark III, but it's definitely a great Rhodes that will give you this classic sound. I'm not sure how readily available this particular model is as I've only used it at a friends house and haven't seen it elsewhere. I would think they aren't around as much as the Mark I's since they were made longer, and in my opinion unless you can find a Mark II cheaper, there's no real reason to go with it over a Mark I. The bottom line is that you really can't go wrong with the Mark II Stage 73 if you're looking for a Rhodes for any purpose...
