I'm in England and am on the lookout for an external DVD writer for use with both my iBook (see sig) and my PC. Though I'd prefer Firewire, I'm seeing that practically all of the ones in my budget (more or less £70 give or take a few quid) are USB2 models. Does anyone here have any experience with any USB2 DVD writers, and if so, how well do they behave with OS X? I know my iBook is supported and stuff for USB2, but I've read a few scare stories suggesting that it's nowhere near as stable/fast/life defining (that last one's maybe taking it a bit far) as a Firewire drive. Some reassurance would be useful. And if you've any links for decent Firewire ones, please let me know. Many thanks.
