@Ron If i was in your shoes, and prefer the 240 as you do, I would certainly inquire about an upgrade, which Leica implies is available.
Another path would be to send the camera in now and see if Leica wants to swap the sensor. Then you have a really sweet camera for sale or to keep whichever you prefer. They will go through it and may replace the shutter and other stuff too. They must replace the leatherette regardless, which is nice.
I was scared to buy an M9 with original sensor even before the latest kerfuffel. Fresh back from Leica your camera is easily worth 3500 today.
Since you are not using it this would not be very inconvenient for you.
