If we could get to that state of relatively smooth, low friction ebook import and conversion with BN, I'd reconsider them as a source for ebooks. I really have no beef with them otherwise, still like their physical stores and give them my business here locally.
My point still stands. Currently, workarounds exist relying on availability of copies using older DRM but as far as I'm aware, the DRM used for Kindle4PC 1.25 or FW5.10.2 has yet to be broken.

Also, I wouldn't consider dealing with kfx easy. Unlike azw3 or mobi, you can't simply drag and drop to Calibre. You'll have to zip the kfx and resources folder first. On Kindle4PC version (which you want if image quality is a concern), files all just unhelpfully use azw and azw.res extension so you don't actually know if a book is kfx or azw3+azw6. Along with cryptic ASIN-based filenames, they're a major pain in the neck when batch processing (particularly when books fail to decrypt).

In my case, the azw3 versions of manga I buy are noticeably lower quality and therefore undesirable compared to Kobo.

I'll have to recheck my external HDD, but one of the test cases:
Found the post.
