Yep, it was scary, but it all worked out well.
I went over some of the things people say to look for. Is the person open about their use of the GPU? Can they show some documentation of the use and temps. Can they be described as a person who mines responsibly, not abusing the equipment? Do they keep track of thermals and provide a dry location with clean cool air? Do they keep the fans running all the time? Do they change the low-grade stock thermal pads with good ones that work well and keep the rig nice and cool?
What is their satisfaction rating on the market?
Buying a used mining GPU might actually be better than buying from a gamer if the miner was conservative in use of the GPU, and if they don't go for extreme overclocking to get that last bit of hash squeezed out at the expense of the chips. But communication is key! You must initiate dialogue and establish trust.
