You won't be able to get a broadcast camera for less than £2-3K - however, the Canon HV20 or HV30 are good quality high definition cameras and out of the box have been seen to match a £3K cam for quality (though the manual controls with a £3K cam allow much more customisation, so is ultimately better). But yeah, an HV20 or HV30 is a good affordable inbetween.
