GrapeCity are my first port of call for anything development based GrapeCity have great people in their sales and technical teams. Their online services take some beating too (I'm yet to find anyone who can!). All in all, a great company to help you with your development tools.

Interesting product Active report is a really interesting product but it's not really finish/polished (web). Documentation is poor. Customer support save this product, even with all problem we are supporting and are willing to help and hotfix showstopper issue.

Spread.Net is fully featured and strong on performance Spread.Net is in my opinion the best product available for implementing Excel-like functionality in a Windows Forms application. It is very strong on feature-set and performance. The on-line support people take an interest and have been able to resolve minor issues we have experienced.

Component One Studio Visual Studio integration I have been using some of your components for some years and they provide seamless integration into Visual Studio. They are fast to render and easy to use with good sample codes.

Great product and support Documents for Excel .Net is a great product. It does everything I need without having to purchase an Excel license for every machine to which I deploy. Their sales team was very responsive to my pre-sale questions. Their free 30-day trial was most helpful in allowing me to run the product through various tests to make sure it would fit my development needs. I have now purchased the product and am using it successfully in production.
