Best GPU for Litecoin

[wndrbr3d]

I'm looking to cash in on the high prices and invest in another LTC rig.

What's the best GPU out there as far as khash/$ is concerned? I'm thinking a $199 deal on a 7850 might be the best deal going but curious if there's any other input on the matter.

Thanks in advance!
