On my main hunter I count 61 ranged weapons, 11 complete tier sets, and 350 total pieces of transmog gear. I guess you could say transmogrification has become somewhat of an obsession of mine. As soon as I heard the feature was coming way back during patch 4.2, I began the hunt to to re-acquire gear I'd possessed in the past, or other gear which I always wished I had while it was relevant but never had the opportunity. It breathed new life into the game for me.
Hunters are well suited for farming transmog gear as we can solo things that other classes can't. We also have the freedom of transmogging any ranged weapon type into another, e.g. a gun into a bow. If you search hard enough, you'll find some really unique pieces out there which allow you to look like you're wearing armor from a different class. For example, did you know there's a mail armor eye patch available?
