Hi Randy,
I've used Dynazip before and didn't have any problems with this product - it worked as advertised and I didn't mean to discourage anyone from using this product.
The big issue for me personally was that Dynazip is an ActiveX component that requires registration. Getting admin permission to install software is a nightmare for my customers so I'm always on the lookout for components that can be used with a minimal of hassles. I also appreciate the small size of the bigspeed component (38K when compressed as part of a setup). I'm not worried about disk space, but download times are always an issue for my customers.
BTW: I really enjoyed your WebRAD book.
