A year or so ago I bought a Bosch 800 series to replace the bargain basement model my house came with and it's been great so far. The Bosch's noise level isn't a problem at all despite being practically in the living room (open floor plan kitchen + living room), and the build quality difference between the two was just staggering… The original cheapo was so light I could carry it around on my own all day long, while the Bosch was so much heavier that moving it was a two-person affair.
