I paid just shy of 50k for mine, and I got them direct from MM. My situation was a bit weird as I bought my ovens as 570’s about three years ago, but did not take delivery on them until a couple months ago. MM held them for me as I was still in the planning stages of my building and by the time I was ready for them the 670 was available so I upgraded to the 670 wow ovens. I can’t wait to use the darn things though, but I just keep having trouble with contractors and getting my building done!!! Hopefully in the next 3 or 4 months though. I have nothing but good to say about MM so far though as they really worked with me. When mine get up and running I will share my feelings on the 670’s with you, and you are of course welcome to come on down and use them yourself. I will be fine tuning my formulation as soon as they are installed so I am sure that will at least a few weeks before we are open so the kitchen will be way under utilized for a while.
