Best place to sell busted DS4?

I have a Dual Shock 4 that works perfectly other than a completely mangled Left Trigger (L2).  Needless to say, the L2 is all messed up.  But otherwise the controller is fine, and could be used for spare parts, experimentation, or whatever else someone can think of to do with it.  Any suggestions on where to post an ad?  I sell a lot of stuff on Amazon, but I'm a little wary of selling something there that doesn't actually work.  I also used to sell more stuff on craigslist, but I don't want to get killed.  Any other suggestions?

Edit:  Oh, and what would be a fair price to ask?

I'm calling the Controller Abuse hotline on you, buddy, and don't even pretend like it "fell down some stairs"!

$.50

But really it looks like you can put it on ebay and possibly get a few bucks for it,  i found a listing for 3 broken DS4 for $77 or best offer.  Maybe you could get $10 to $25 for it on ebay.
