Sold mine recently for 195$ body only, really rough user but in good operating order.
My first S2 cost me 400$ in 2014 in excellent condition. Both without lens.
I think prices are a little low right now for sellers, but still catching more than their Contax cousins. So all in all, a good thing as they are more approachable at the current prices for those wanting to try Nikon RF.
I wish the glass would take a little price slash! 😉
