Not bad, if you can handle it first.
There have been a handful shipped that were poorly constructed (warped, machining off). Make sure the string is CENTERED in the limbs when assembled/strung and the limbs are not twisted.
It's not a bad bow, I've shot it one. It's not great, either. Just don't buy one sight unseen! It'll be a fine starter bow.
As for vibration or noise, twisting the string to adjust brace height is usually all it takes to get rid of most of it.
I'd recommend the 45lb if you plan to hunt with it - and measure it first. Sometimes they aren't quite as advertised.
That being said, it'll be easier to learn proper form (which is uber-important in traditional shooting) with a lighter draw weight.
