On the presumption that the reason you want a mouse is because you're not in love with the trackpad, I'd guess that any recommendation for a mouse that's actually a mouse/trackpad hybrid is going to be shot down, especially when you can get a Logitech mouse for less than 25% of the price. Nothing wrong with either the Logitech or Microsoft variants, other than that they're traditional mice. Go down to the store, try out a few, and see which feels best in your hand. If you end up hating it, you won't be out much money.
In defense of Magic Mouse, I don't know about "overpriced for what it is." It's in a category of its own, and it's something that you need to get used to. I think it's more likely that the problem people have is, "If it's going to be $70, I damn well better fall in love with it at first touch." But it is something of an acquired taste, an acquired skill. Like a trackpad, it's prone to unintended acts until you get used to the idea that every movement does something.
I definitely prefer the track wheel/trackball-equivalent swipe, I love swipe-left, swipe-right to browser-back, browser-forward. Every so often I accidentally tap-to-zoom, and every so often, the unintended browser-back that ends up wiping the contents of a Reply to Thread window... not so much fun. But if I wanted to, I could disable those gestures.
My basic feeling is, OS X is only going to gain more touchscreen-like gestures, and I'd rather move one or two fingers around on a Magic Mouse than my entire hand/wrist (or make big motions of my arm across a vertical screen). It's definitely saving me steps/motion over an equivalent mouse. I'm happy I have it.
