I've used my friend's Rainbow vacuum, I'm a hyuge fan. He offered me a refurbed one for $600 and I almost bought it. Having the dust/debris collect in water seems much cleaner then bags/bagless. I've never used a Miele though.
It is so hard to find a chicken under 3 lbs here. Almost all of the stores only have 5.5 lbs+. Trying to make Thomas Keller's fried chicken and he really recommends a smaller bird for better skin-to-meat ratio.
