RE: "I can get a cheap adapter from Amazon, thanks."
I assume you mean a cheap adapter that attaches to the computer via USB, and to the camcorder via its analog video outputs. Those should work fine, provided that you get one that's compatible with your Mac.
Just in case: if you see a device that claims to be a "USB to Firewire adapter", avoid it like the plague. You can't add a Firewire port using a USB-A adapter. But there are some vendors who have glued a USB-A connector to a Firewire connector anyway!
What that means is that the wires are connected randomly inside – if they are connected at all. At best, it won't work, and possibly it will even fry something. There was a review of one such device on Amazon where the guy said that he should have known it wouldn't work, but he bought it anyway. It concluded with a statement to the effect of "Woe is me, for today I am not engineer." (!!!)
