I was shopping for a directory PHP script when I found PHP Links Directory. I looked for weeks and evaluated every "directory" option available. My very first email asking questions was promptly responded to, whereas I have yet to receive anything from competitors. As I made my decision to buy their product, they have been incredibly fast and efficient in helping me with everything. They did a free installation, they have made some tweaks to customize for me and have just been all around great to work with. I highly recommend this product and company to anyone looking for a directory script.
