You can get a decent DSLR and a good lens for less than a mirrorless camera body. https://www.dpreview.com/ has a good archive of detailed camera reviews, even on older models, so you can do some research. Think about pros and cons of full sensor vs. crop sensor, what features you will want, what lenses are compatible. Ask sellers for shutter count - lower numbers mean your used camera will have a longer life. Good luck!

Turned out this old camera is a mirrorless, and it's not working due to battery / power issues. Probably will fix it, if not I'll buy a Sony or Canon mirrorless 📸
