Phillip the more I get used to CT the more I can see it is an excellent script.
It has quite a lot of integration bridges/ lots of modules/ masses of customising power/ some powerful innovations like using forums for comment discussion.

But it has some big barriers too.
One is the price. Because it is such a big complex and powerful script it is worth the price. But for many people it's still a fairly high price to pay in one payment.
The other is the complexity. Again because it has so many functions it is a big collection of things to learn.

My suggestion therefore is that you split Contentteller into 2 versions.

Standard Contentteller - cuts the options to one module.
If not too hard to code three Standard versions make this a buyer choice of Articles, Content or News.If this is too much just Articles.
Price is E55.
Upgrade to Superior later E45 so you receive another set of files to install.
Not only would the price be easier to manage for many, but the buyer gets a much simpler admin area. Once the buyer learns to manage one module they will be able to manage the others easily.

Superior Contentteller - all the modules as now. E87
