Cheerful, despite his short stature, ragged clothes and gun-bluing all over him, Buster is an exemplary weapons merchant, selling high quality weapons at affordable prices. He is a true weapons nut and loves working with them, including upgrades - whenever he has an attachment available, he is willing to sell it to a professional looking for quality.
