I use dbpoweramp to convert to WAV files and then transfer them to itunes and convert to apple lossless for my ipod. I've been using it for a few years now, but dbpoweramp is not free, i think its ten or twenty bucks. I have probably converted over a hundred gigs of music though because there are free flac downloads of my favorite music so it was worth it to get all those cd quality files and play them on my ipod for free even it it did cost a little for the program. edit-wait i reread the question, you are going to convert those lossless files to mp3s-what! ouch.
