This doesn't match your requirements exactly but isn't bad for the money. I've got one and can't complain about anything with it apart from the blacks going very hazy when not in the correct viewing cone (but that's LCD for ya). The speakers aren't too bad considering, but there's also an output for a sub-woofer if you want to beef it up a bit.
