Spending tons of cash on used gear used to make me so nervous because I am super cautious! Finding a marketplace that actually does hands-on testing was amazing tho. When I bought my current setup, they sent over a full inspection report before they even shipped it to me. The whole experience was just fantastic! Basically, these big reputable sites have actual technicians who check for fungus in glass and verify the shutter count on the bodies. It taught me that real certification comes from these in-house experts, not just a random seller saying it works. Ngl, getting that verified gear in the mail felt amazing because I knew it wasnt a total dud. Love the peace of mind that comes with a real inspection process!
