getsammyb - from the tone of your posts you might want to try out the new Magix Audio Cleaning Lab 10 - I've been using the ACLs for a few years now and it's real easy to throw together a quick DIY master in there (not talking about a master worthy of repro - I don't do that). ACL has wizards for any repair, EQ, dynamics balancing you may need to perform on your mix to give you a hand in case you don't happen to have Massive or Blue Bear leanin over your shoulder givin you tips.
I'm pretty pleased with ACL10 (just got it in the mail this weekend) and I leave CD Architect, Audition 1.5, Sonar4, Soundforge in the drawer for the quick repair, balancing and CD writing features ACL has:

I'm not dissin the other stuff but I think you will appreciate honing your skills on something 1/10 the price of Wavelab...unless you're mastering something for pro distribution - it didn't sound like you were.
