I would not buy a leo as your first ray unless you are 100% confident your system is up to it as it would be a shame to spend £600 only for you to loose it because of inexperience. If you do go for the leo i definately would not put a puffer of any kind in with it as it will only end in tatters. Sorry if it sounds like im trying to do anyone out of a sale but im only looking out for the rays best interests an no one elses.
