Wow, I wish I would have held out for this bad boy, I can see several features on this I like better than my MM16, the guides are definitely superior and the fence system looks WAY better than the one on the MM16. I also like the the throat plate setup better and blade guard system though it does have a shorter resaw capacity. Can you get that fence setup and replace the one on the MM16, i mean the fence setup is far superior the one on the MM16 leaves much to be desired. I really like this saw, that's not to say I don't love my MM16, I do, but I definitely like a few things better on this saw.
machineatlas.com/machines/scm-minimax-s-400p-mm16/ Here it says that MM16 is better. "It is slightly smaller than SCM’s other entry-level band saw (the Minimax S 45n), but has more and better quality features, like a sturdier fence, blade tension control wheel, easily replaceable rubber tires. Another difference is that the S 400P has almost fully closed wheels, while the S 45N has more gaps in them (making them lighter). "
I believe the mobility solution was added when the model number went from S 45 to S 45N, maybe early - mid 00s. If your machine is green, yellow or red it definitely wasn't available then.
