I did have the same decision to make last year.
I purchased the 600D (T3i) with the 18-55 kit and a 70-200 F4 L is.
I was using Minolta SLR for long. Then moved to Canon G9 then G10.
What I can say is that I have been very disappointed by the lack “pleasure” to use the 600D. I found it not easy to use if you want to setup manually.
The image quality is very good, with the 70-200L you get quality you don’t even think the sensor is capable of
. The lens make the difference.
In the price range, the 7D is a bit bulky and heavy. The 5D2 does not have a built in flash.
I would definitively go for 60D unless you are doing a lot of video (for video, 650D is better).
The replacement should arrive in a few month but I suspect the price of the new model will be much higher
So now, I would get the best deal on 60D to get a very good camera.
If there is some cash left, the 17-55 is just amazing. Try to get a good second hand one.
Otherwise, the 18-135 is a very good all-purpose travel lens.
Anyway, welcome to this forum.
