Our small company decided to go with DevExpress because of their reputation and solid products, and I must say am I glad we did. We initially only needed a few components in their suite, but as our requirements changed and we needed more, it was sure nice to be able to get matching components without having to go to another company. They have it all! Also, I've felt the documentation to be fair for the components we've used. There online support system is top notch too. Questions are usually addressed within a day.
