Is the fujifilm x t200 worth buying used?
Yes, I think the X-T200 is a good used buy. It's an entry-level mirrorless body with a 24.2-megapixel APS-C sensor and a large vari-angle screen, and as my buying used guide says, a body a generation or two old is often most of the camera for much less money.
Before you buy, check two things. There's no stabilisation in the body, so pair it with stabilised lenses for slow shutter speeds, such as the Fujifilm XF 18-55mm f/2.8-4 R LM OIS or the Fujifilm XC 15-45mm f/3.5-5.6 OIS PZ. And budget for a new genuine battery, because old ones lose capacity. The X-T200 page has the full list of lenses that fit it.
