It's only an opinion, but I am in IT and have been for 8 years, so.......
I feel a computer burner will meet all of your needs. I use a burner in my PC and have done side by side tests with factory created CDs and could not hear a difference. I really can't see logical reasons why a dedicated burner would record the 1s and 0s any differently than a computer's burner. If anything, the media you use should make the biggest difference as you are burning (literally) the media and how the media reacts to that could affect sound, so use good media.
Now, more to my expertise in computers, unless you are looking to upgrade and buy a new computer, simply buy an external burner. I'm not 100% familiar with Macs that are 6 years old, but if possible, buy a USB 2.0 card for your Mac and buy a USB 2.0 compatible External burner and you'll be set. I'd also recommend the name brand Plextor; its a solid brand and isn't the most expensive on the shelf.
If you can upgrade your computer, just about anything you buy these days will come with a burner.
Side note; a burner used on your computer also gives you much more functionality than a dedicated CD burner. Money well spent in my opinion.
Good luck.
