Look at the Grizzly G0636X as an alternative. Just as much power and resaw height. The switch works. The fence is far superior. The dust collection is far better. The table tilt adjustment system is far more robust. And the manual is infinitely better. I don't know if the frame is any more stiff than on the MM-16 but I do know that the G0636X can easily tension a 1" blade to 25K psi, and a lot more if desired. And it costs substantially less. I've had one for about 2-1/2 years and have run thousands of feet of wood through it. With a carbide blade on it it is scary fast. I smile every time I use it.
No matter what you buy the comment about needing good DC is no joke. You will need at least 800 real CFM to effectively remove all the sawdust these things throw when resawing something 12" thick. I had to completely reconfigure my 2 HP DC system in order to do it. Good luck.
