I highly recommend CMS-Master as a product and in Particular Conkurent as a company. I have now worked with and used CMS-Master for 5 months, and Conkurent has helped me with several projects for my customers. I have worked with several CMS systems in the past, both very complex, expensive and some simple and inexpensive. And CMS-Master certainly belongs in the last category, Simple and Cheap. But it delivers more than any other simple CMS system I have dealt with.
Last but not least, CMS-Master can be fully customized to your needs. So if you need a special module, just ask them.
