I have now bought a camera and two lenses. I ended up buying a 60D (new) with an EF-S 17-55mm f/2.8 IS USM (used). After two weeks I bought the 70-300mm f/4-5.6L IS USM (new).
This is a gigantic step upwards from my 9G compact and I absolutely love it!
All the new controls, settings, the way to shoot and the viewfinder is all very different – but in a good way.
The most significant changes over the G9 are obviously speed and image quality.
I my opinion the 17-55 makes a good focal length for all-round group pictures and landscapes plus for indoor use. The 70-300L is absolutely useless for that. But for details, animals and far away objects it’s amazing! I can’t wait to get to Malaysia and shoot some wildlife. I this this is really where the 70-300L will shine
