I may still get a Plex someday, but with the advent of SafeDisk 3 and Securom 4.8 (which rendered essentially all burners useless for awhile) I stopped worrying about "perfect" backups of my PC game collection. I "caved" so to speak.
Now I back them up best I can and use a NO CD fix or emulation if I have too. The legality of which is debatable.
Then comes along the new Plex that can back up the newest Securom. This "cat and mouse" game is good for CD burner manufacturers and game developers, not the consumer. The day this burner can be found for $50 then I'll get it, but of course Securom 6 will be out by then.
So in the meantime I'll work on turning my Xbox in to a monster machine.
To stay on topic, my kids are getting a Karaoke machine for Xmas and I will be putting my CD+G burners to the test. The HP I know works as it has been used to backup a commercial CD+G on loan to a friend of mine.
