I can't find this model on Trademe to reference for selling value. There are some Ryzen 5 versions with onboard Radeon Vega graphics from $950 & up, so not really comparable.
A new Pavilion 15 with Ryzen 7 will cost you $3k+, a new Pavilion with Ryzen 5 & 1650TI is $1780 @ PB Tech.
So I think that $800 is a pretty good deal for GZ members.
