I've had good luck with their components in the past.

>I have been using XZip/Unzip30 from Softuarium for quite a few years now, but a client has a new server and it will not register. Having spent enough time trying to figure that out, I thought I would ask the community and find out what is the most popular control right now and make a switch to something newer. So what are you using?
