This makes this component about 10-15x times smaller than most 3rd party ActiveX components like DynaZip. Its also about 2-3x faster than the version of Dynazip that shipped about a year ago. Finally, at $65, its $200-$300 cheaper.

I've used DynaZip for a long time, and while I grant it is more expensive, I have no complaints. We have a wrapper class that handles lots of common functionality. As to speed, we found that if you changed the compression setting to trade off size and speed differently from the default, DynaZip would run alot faster, without the size growing unacceptably. Our default now sets the CompressionFactor property to 2, which my notes say is "good performance, OK compression".
