I would look to a different dealer than the one giving you bum information. Like Jim said, Hobby People/ Global Hobby is the service arm. I have a 52, a 70, and two 91 magnum four strokes and they are all great engines. Hobby People is second to none when it comes to customer support.

Also the price difference is a bit more than $40- $50. Tower sell both brands. The O.S. 91 Surpass is $249.99, and the Magnum 91rfs is $169.99. I have also had O.S. four strokes and I personally can't see the $80 difference between the two. You could, if you wanted bragging rights, put a black OS rocker on your Mag for about $17.
