I want to take some causal pictures.Definitely buy a used camera, I have done so for many many years, doesn't matter if you are new to photography.
I would recommend any decent entry level camera for learning, the market is flooded.
You just have to make up your mind what is it exactly you are looking for, what kind of photography do you like, budget,... And then we can help you recommend cameras and lenses
Then just get a nice used beginners camera with standard lens and you will be more than happy. This will make you learn more about photography and then later on you can get more specific lenses.I want to take some causal pictures.
one such place claimed to be a REPAIR store as well, but could not understand a person would want a refund when a camera sold as fully functional despite the fact that a knob that LOCKS and UNLOCKS the shutter trigger button from moving was frozen in place...and "camera shops" are not reliable sources of anything anymore. most of the used stuff they sell like ebay is "refurbished" simply by rubbing it with a wet wipe.
I have bought two used cameras online from "established before 1990" camera shops, they had no "idea a camera was broken even though most electrical functions did not work or realize a camera is damaged when dials and knobs do not move
