If you really want Godzilla and have this offer pending, you need to decide to take it or move along. My opinion is if you are done with R&M you have the potential for a win-win deal here. Maybe try to play the LE machine and Pro if you can find one so you can make a more educated choice.
We can't tell you which machines you really like and want to hold on to or which after being sold will cause buyer's remorse .
Good luck - a great first world problem to have .
