Should I adopt a dog from a rescue or from a breeder?

I know exactly the dog breed I want, mini schnauzer, but don't know where to get it from. I love the concept of rescues but like the information on the dog that the breeder can provide. In my area, rescues and breeders adopt the dog for the same price - so that really isn't a factor. I tend towards a breeder but my heart strings tug me in the direction of a rescue. I've done a lot of research on both and know the benefits and drawbacks, but I can't make up my mind.. help!
