The extra assurrance we provide is single vendor responsibility and one-stop support. Speaking of price, the overall bundle is a discounted from the list prices of the total of the components. You can pay more and you can pay less, but there isn't a better value around. This is the only format that most replicators will accept. Of course we will sell the items a la carte but the discounts are not as deep and, depending on your choices, we can't provide as complete support because it's your system, not ours.
Prices are different.
The DVDAuthorQuick authoring system is available in addition to or instead of CDMotion. It offers some additional features, but is not nearly as easy to use. The DLT is deletable. Not required if you only want one-off discs. The Pioneer DVR-S201 is deletable.
