Another recommendation for Verbatim here as well.
I used to use Memorex, but the layer break gave me too many problems. Basically, as the player started approaching the data near the layer break, it would start to stutter until it wasn't reading any data anymore. I created a lot of coasters before I abandoned them.
Since I've used Verbatim, I've only created one coaster and that was my fault really for using the wrong settings.
