Has anyone used Expresta?
Expresta also offers a hybrid model. You can print only 10 books, and they have a warehouse where they store them. The shipping is next-day, which is quite fast. They always keep the 10-book stock. It is a service in the EU. It could be a good place to sell your book if you have customers inside the EU. I took a quick look, and the issue is that their book sizes are not compatible with Amazon KDP. The book needs a new design to match the metric system. It could work for a hardcover version if there is a demand in the EU for your book. Any experience with the print quality, etc.
