Tracy,
I've been using SDT for about four years. In fact I've been using it to build tables for a new app almost the entire day today. Doug has always responded to requests for support and other issues very fast and very helpfully. Their office keeps us informed when new releases are available. I use it with Visual MaxFrame Professional from Visionpace, Inc. and the set up for the two to work together is very easy and dependable. I would highly recommend this product as high value for the cost.
