We like Bosch, but not sure if they have any in that price range. Our last one was super quiet - I think 45 dB, or was it 48? - something like that. I didn't even mind having it running while I was in the living room watching TV, and usually those kind of distractions get under my skin.
Another nice thing about Bosch is that they have a sensor that does not allow it to run if there is a water leak present. Could save repair bills later.
