What price should I charge?

I'm asking my question again because the other one wasn't well formulated. What price should\can I charge for a sony a200 and a nikon d60 with two lenses and all their accessories (including 2 bags)? I really want to buy a canon dos t3i.

Either you to the library or a bookstore and look for a book on used cameras value. If you don't like to read then going to the eBay site and try and find a model similar to yours. I just sold a lens and there were five other competitors. I really was serious about selling so I listed my lens cheaper by $10.00 then all the others. If you can find a full line camera shop that sells used cameras, you should get a price quote on your stuff. Then double the amount they would give you. This will place you in the ball park of value.

Look for prices in Ebay or any other merchants that sells second hand items. Of course consider also the depreciation of that items. How many years or months do you use that items is also a factor.
