Another vote for the 7D. £500 for a good second hand one, £650 from HK or just under £1k in UK. There is talk of a MKii coming out soon but that has been talk for years now and it will no doubt be twice as much.
I have had a 500D, 600D, 40D and borrowed a 60D and the 7D is superior to all of them in handling, fps and auto-focus.
Flippy screens are only there to break and are only useful for macro and video IMO.
