I found a local D7100 for $550. She is trying to get the shutter on for me right now but says it's very low less than 200 as a guess.
Also found another with 11014 clicks for $385.
I bought my D7100 refurbished directly from Nikon and never experienced any issues. I really need to put mine up for sale because it's been sitting here unused since April 2018. The last post I can find here is this one: https://nikonites.com/project-365-and-daily-photos/41133-hark-2018-a-2.html#post665816
The file number of that last image is DSC_3775 so I'm guessing my shutter count is less than 4000. If you are interested, let me know and I'll post some pics in the Marketplace and verify the shutter count. Seriously this body has very sharp images - and only had 39 shutter actuations when I bought it. Mostly used inside for theater photos. If you aren't interested, that's fine, too. I really need to put a couple things up for sale so maybe this will motivate me to do so.
