libdib@RNDC is it worth it?

[aw_]

I've heard some folks have good success with libdib. But haven't heard anyone mention libdib@rndc.
I assumed it would just be libdib with RNDC's name on it for legal reasons. But then we got to pricing and i'm scratching my head as to how this is worth it.

Everything I've read says I'd ship through fedex, and libdib/rndc would provide no sales or marketing support. The typical libdib model is they take 14% which seems reasonable to me for that service. But libdib@RNDC is a minimum of "28%" but they use some fun math calculating that, they actually are asking for around 45%.

Is there something I'm missing that would justify that price? Does anyone have any experience with this?
