Yes, I also thought the tutorial was fantastic.
I made exact copies of his channel strip settings for guitar, rhodes, strings, bass, etc., none of which use 3rd-party plug-ins. But yes, the mastering plug-ins are very expensive, except Izotope Ozone 3. David seemed to really like that one and I got it from MusiciansFriend for only $200. I just haven't figured out how to make it appear in Logic yet...
