Price on Used Equipment + Next steps?

[jjphotos]

Hey guys, I'm looking to upgrade my camera after 4 years. I've been still using the Canon T3i for quite a while now. I also have the 55-250mm lens, 50mm 1.8 lens and the kit 18-55mm lens. Just wondering what I resell these for roughly. I should mention they are probably only in good condition, but not the best since it has been 4 years. Sorry if this is the wrong section.

You can go to ebay and search for an item and see how much it was sold recently. And you can also go to keh.com and see how much they are selling it right now. Of course, price is also based on the condition of the item you are trying to sell.
