I sold cameras for 20 years, but I can't help you without knowing a bit more. If you have no experience, start with a simple, easy to learn camera without having to buy a lot of lenses or other stuff. This can be a second or backup camera later if you want to move up. Most Americans use cameras as sort of diary, and a snapshot camera is fine for that--some are very fine quality. I would buy the best bargain (new) I can find, in the price range or category I want. I buy used, but I am an experienced user/buyer. You do not need what the pros use unless you are trying to go pro--and even then, maybe not. If you do have experience, go by your experience, or look for advice in a good camera store (if they still have those). There are so many fine cameras at bargain prices, I would not know where to start, especially without knowing what you are interested in.
