As all you know, iMacs don't support surround sound, which usb device would you guys suggest to get. Keep in mind that I may also get the EyeTV 250 so the sound card will need to work with this as well. I'm sure there's no problem, but I havn't done too much research yet. i should also add I'm considering getting a Wii, so i'd like to be able to hook it up to my iMac as well.
