A used Canon D350 and a good lens a really good buy.
Remember that until you are hitting the top ranges of these DSLRs, you are getting the same sensor, so you are paying all that extra $$$ for the software features, and faster FPS.
Go manual, get a good spot meter and learn the zone system, best thing I ever did.
It's amazing how good pictures an old D350 can take with a good lens. My absolute favorite lens is Canon ef 85mm f/1.8 USM, it's a non zoom so it forces you to move to your targets instead of standing at the same spot zooming, and it has a very smooth background blur, it's basically L quality lens for non-L price.
