Let me put it like this.

Before the KO's started appearing I often saw complete Gnaw's go for over $100.

I snared one off E-Bay the other day for $126 including shipping. A day after I got mine another one was listed with a B.I.N. of $140, both were from trust worthy sellers so I don't doubt the 2nd one was legit like mine.

Now with knock offs flooding the market you're going to be harder pressed to find a genuine, complete, and cheap Gnaw.
