I was looking to find a way to buy used equipment

"I'm planning to participate in Olympic games against the best athletes of the planet. I plan to buy a few used sneakers of a similar size than my feet and a second hand tennis racket that is not too worned out. I plan to win against people with brand new and tailor-made equipment".

In short. Don't do it unless you know what you are buying. If you know what you are buying, don't do it if you can afford doing otherwise.

In most cases used equipment will be sold because either the lab had been crushed by better equipped competitors, or is obsolete.
