I recently purchased an MX for 59 with the 50/1.7 lens from a dealer with 3 months guarantee. There was another one in stock at the same time. The attraction for me was to have a camera with only basic controls and no battery dependency (except the meter, and battery-less meters of that period are probably not dependable now).

No way will I be selling mine, as it is special, whereas I suspect the ME is just another example of a 35mm SLR with too many buttons, and more likely to be sold.
