dump the removable flash memory based cards. get a camera with fixed flash and/or harddisk.
no camera has fixed flash, even less pro/prosumer equipment.
hdd are not used anymore in cameras either, i do remember some consumer sony handycam that had hdd back some year ago, in the prosumer camp you need to be able to swap out memory without having to move the entire camera with you
? really ? what planet are you from ?

how many more do i need to list ?
I have two sony harddisk based machines that i use for underwater. (one 320Gbyte and one 250Gbyte) work perfectly fine :
Advice to dave : Go on ebay and buy a few used HDD based camcorders. shoot from different angles. simply plug in usb and copy files over.
SD cards are unreliable. I have a camcorder with Sd card. bump it while filing and you have corrupted files. the problem is the edge wiping contact of SD cards.
Compactflash is much more robust. that uses a real pinheader.
-edit- i just went to ebay. there's plenty 30Gb--60Gbyte HD camcorders used for between 60 to 200$.. you can get two or three for the price of one.
