They are pretty expensive, but I had a guy offer me an LEO (EW-08) for $200 new. They sell for $435, and I like the look of them, and the features. I'm really considering giving it a try. I have personal experience with Surefire lights and they are top notch, from what I know their suppressors are as well. I'm thinking I'm going to give it a try, it is this knife, what do you think: http://www.surefire.com/EW-08
