So I have been trying to sell some old vintage cameras I found in my attic here in Ohio because I really need the extra cash for rent next month. I have no idea how much these things are actually worth and I keep seeing people say to check sold listings on eBay but its honestly super confusing. Every time I try to look up stuff the site keeps pestering me to sign in or create an account and I really dont want to give them my info just to see what a camera sold for three months ago. I tried googling it but all the sites that pop up look kinda sketchy or make me sign up for a paid subscription which I definitely cant afford right now.

Is there anything simple I can use that doesnt track me or demand a login? I just want to see what things have sold for so I dont end up getting ripped off when I list them. Im sorry if this is a totally dumb question but I am just really out of my depth here and have never sold anything online before. Are there any actual reliable tools for this that just let you type in the item and see the data without all the sign up nonsense?
