what did you find lacking in the 75-300 - just the reach?
A 500mm would fit the bill if it was autofocus?

i would like something bigger but which one,there are so many about and i am new to wildlife photography

For what you want to do and the amount you have to spend, the used market may have something of interest. I don't think you can do it new. In fact, I'm not sure you can find something significantly better than the 75-300 in the used market with autofocus. Longer and faster than the 300 f5.6... 300f4; 300 f2.8 400f4, 400f2.8... all those are significantly out of your price range if you can even find them in your mount. In general you may find limited selection/availability in fast teles or tele zooms in Sony mount.
