The tilt screen on the 60D was a factor for me too. I had a tilting screen on my Sony and used it a lot, so I would have missed that.
The live view mode on the 60D is better than the 7D I think, and live view is better still on the 70D.
If you can afford a 7D or a 70D, then go for it. The 7D does have a higher build quality (though the 60D doesn't feel cheap at all) and better fps, but it's now an old model and I think due for replacement.
As I said, if you're spending that much I would probably want the latest model rather than an old model, particularly a crop sensor.
A grand; if you want new, get the 70D, if you want full frame goodness, get a 5D2.
I guess once all the stocks of 60D have gone, then the price of the 70D will come down a little.
Buying the 60D was the best option for me anyway and if you had a grand budget, then that would give you £500 for some really nice glass (Canon 17-55 f2.8 or 24-105 f4 L).
One slight annoyance with swapping to the 60D is that it uses SD cards rather than compact flash, so I had to ditch my CF cards. Mind you, HDEW bundled a Sandisk Extreme 8GB SD card with the camera for free, so that was fine.
I'll have to get hold of my brother's 7D and do some side by side comparisons.
