The MRE is no longer available but you may still find one from some suppliers.
You should still be able get the MSXX which is the current model. I think the original MSX and 415MS are all discontinued.

But you should also look at the TA05MS coming very soon. It is very close to the MRE. Just the motor mount, lay shaft and drive train is different.

Similar price to MSXX but with 2.5mm lower deck as standard.
