Hi, I'm going to be ordering a new iMac next week and I'm concerned about only having one FW port. I often have more than one external FW hard drive connected and a tape deck. Does anyone have any suggestion on how to add ports. I've found that there are very few FW hubs.. especially that have FW800 capabilities. I know I can connect each device to one another, however, that is not efficient when having tom eject some drives and connect other. Thanks very much!
