Would you be willing to try it? It is only $19.99 for the full app. Either 64-bit or 32-bit. You can generate Kindle Ebooks with it (not just static but interactive ones, (just Google the Kindle Plugin for Page Plus 9,) and so much more.
It is the best $20 I have ever spent. It isn't anything like Microsoft Publisher, and it really is more like a true DTP application. You can do layers and graphic editing (I love their Cutout Studio). It will let you work with EPS and SVG files, and import and edit pdf files, as well. It also has pdf form creation functionality. It isn't InDesign, but it offers almost as much, and a few more bells and whistles. I love their autoflow feature for inserting large amounts of graphic files with just the push of a button. You can link your text boxes, do intricate page sizes, N-up.... Different master pages, also different layouts in a publication. Crop marks and imposition as well. Plus merge. AND it comes with Avery label templates, which I didn't find in InDesign.
I had to do a very complicated layout for miniaturizing a book, which took me forever to figure out. (I bind books and wanted to make a perfect replica of a full size book.) Scanning the book wasn't the problem. Printing front and back on miniature pages and making sure the right pages are printing front and back, and then setting up my crop marks for cutting. That was my problem. It was very tricky. Once I got my foundation file set up, I could do a 218-page book in under 30 minutes. I couldn't have done it so easily without their stellar asset manager. After all the pages were cut and folded and ready to be bound, it was absolutely perfect.

I don't think they have it for Mac, if you are on Mac. Which you probably are. But if you can swing this, please try it. Thanks so much for your feedback. I appreciate it that you took the time to read my post and respond.
