It's now 2012, and it shouldn't have to be stated, but please do NOT visit or even acknowledge QuackViper's website. It is simply mind-blowing that people put any faith into his site, or are completely unaware of why he's known as QuackViper around the enthusiast community. There are honestly forums you'd be banned from for simply mentioning his site!
