Finds.ly is essensially the new QC finder,

Simply enter your desired seller link and finds.ly will search every agent to provide you with real photos of that seller link

Also they offer a lot of cool finds for FREE, keep in mind most of there items are not 1:1 to retail.

If Kor did not exists I'd be using reddit as my main source of new finds.
