If my memory serves then not much wrong with it tbh. Decent IQ and reasonable fast af. iirc it has a plastic mount so will be susceptible to breaking there if roughly handled and it has a fair bit of distortion at both ends of the zoom. For the price of them though, a decent lens imo.
I'm not 100% sure but isn't that the lens that sometimes comes as a bundle option like a kit lens. Maybe with some of the mid range nikon cameras? If it is I imagine there will be more floating about to sell.
There's nothing to worry about, its a very good all rounder lens. The quantity is due to the majority of people upgrading.
