Panasonic GS75, JVC GRD290 or Sony DVD101

I've been looking for camcorder/camera package or 1 unit to do both. My budget is around £500 and use will be mainly holidays/family occasions etc. Internet is great but suffering from information overload!!!!!
I went round the high street and in 3 different outlets got recommended Panasonic GS75, Sony DVD101 and JVC GRD290. Can anyone recommend any of these or suggest an alternative ?
I get the feeling min DV is the way to go but not sure about 1 or 3 CCDs. Thanks in anticipation.
