I've always used MG motors. I just recently bought my first MK Edge 70. If you buy new, you have to check it very closely. I had to turn the head around on it because it was installed 180* out. Imagine that. So instead of going forward I would go backward. I have only used it once, so I am still not sure what I think of MK. But like the others have said, go with bigger than you think you might need. I went from a 36# to a 70#. Huge difference. Really helps get you out of a cove when the wind is pushing you farther in.
