Just don't buy more equipment than you need, and I say that because this doesn't really replace or make any other equipment you could buy obsolete, unless you are looking for a good quality baseline input thats portable, in a realistic sense

The build quality is fine, it's not particularly solid but the knobs, wheels, and keys are responsive enough for a device in this price range.
