We used inkSoft for many years and the best part was the front-end interface to end customers allows for orders to be placed. They used to have a great way to market editable designs. Not so much anymore. But their customer side for single unchangable shirts is OK.

The design tool would have been helpful, had anyone wanted to use it.

It is easy to pick up how to use the program without any prior experience. You do not necessarily need to have a background in web design to create useable and attractive designs.
