Canon does not offer a full frame mirrorless currently, but there are rumors that one is coming very soon.
@josiahw, the Canon EOS R is now here! https://www.the-digital-picture.com/News/News-Post.aspx?News=28500
since refurbished are inspected so closely when fixed that sometimes they are less risky than a regular purchase
@rachellen Also, when I got my first camera, daddy just searched ‘used camera stores’ and we drove to the closest one! 😀 I had a good experience there and got my first camera for $300 off, (which was much appreciated!! 😀 ) but I can’t say that every store will be good 😀 But you probably already thought of that 😉 😀
@rachellen, I’m afraid I can’t give much advice on a full frame Canon, because I use a crop-sensor Nikon D7000, but I’ve had good results buying used photography equipment from mbp and KEH. I’ve also heard good things about Adorama.
Hope that helps! 🙂
