I went through the same thing when considering what CAI I wanted. I'm the type of person who likes to research stuff before spending my money. Nothing wrong with that. If you're like me and can't make your own, then that's ofcourse not an option. After hours of looking and searching around here, I went with the SLP CAI. It's about the same price and everyone likes the looks of it. Looks to me aren't as important as power, but when power isn't changing between brands, why not get something that looks nice?? That's just my .02
