i know this is in AUD, atm itd be $560 USD, has a 40GB hard disk.
ok i looked on best buy, theres a 30GB version of it, thats 500USD
as for HD, that's outta your price range - heres the cheapest HDD based highdef camera, thats 799USD
the everio ones have nightmode, also the everio i have has a little light on it, dunno if thats of any use.
the only cameras that can record high def in your price range either record to tape, those little dvds, or SD card
