Haven't tried the bio grips but with disposables the vibration is on par with bizarre v2, halo, and inkjecta S3. With stainless I don't even notice it really. The machine has a buzz to it but not as bad as a coil by any means especially loaded and hitting skin but the vibration is nowhere near as bad as that buzz would have you believe. I honestly think this would be a great machine for your situation Limey. They are amazing with ttechs too! The vice tolerances on the tube stem hole are so perfect with the screw swap it is a rock solid vice! And it's so light and well balanced it honestly just feels like you're holding a tube without a machine.
