I have a Clarke (worked fine for buzzing back on, always breaker bar to remove) gun, 24v I think, which can be yours, boxed with light useage, two batteries and charger for £50. Drop me a PM if you're interested.
As Chris said, Snappy guns will remove, but are obscene expensive, do what I did (12 years motorsport industry) and buy a cheap gun to buzz on with, and a decent Mac animal bar to get them off.
Don't rely on any gun for the correct torque - always follow up with a Torque wrench.
