I had a pair of 700 or 701s that underwhelmed me with their build qulity, with among other things a rattling baffle and coming apart at the corners. They sound OK good sound stage but made brass instruments sound like synthesizer IMO. OTOH I have seen photos of some nice looking Missions, and many here who's opinions I respect seem to like them well so maybe I just go lemons, shrug.
Anyway my advice would be to look at them carefully and listen to them and see if you like them, just giving my experience and no disrespect meant, etc.
