David,
as far as the NanoVNA-F is concerned, I'm sorry but I have to disappoint you. We do not own an F-model and have no intentions to buy one, so chances are very low that we will extend our book there. However, as a member of this forum you will be aware of the talk concerning the NanoVNA-H V2. Depending on the final outcome of this model (features and pricing) we might extend the book accordingly.
I haven't been aware of Lulu up to now, but will check into that.

=================================
Noted, Chris.
I would hope that if you asked the makers on the NanoVNA-F, they would provide you with one on loan, perhaps to keep, as your book has obviously proved popular based on the feedback here. Of course, having the NanoVNA-F in your book would help to increase their sales.
Yes, I'm aware of the possibility of a newer model, and I would likely get one if:
- the coverage is significantly greater (3.5 GHz minimum, 6 GHz highly desirable for 5 cm etc.).
- it works with present software (e.g. NanoVNA-saver).
- the screen size is at least "4 inches".
- the size is similar to the present NanoVNA-F.
- the price is similar to the present NanoVNA-F.
Whether it comes from the NanoVNA or the NanoVNA-F suppliers wouldn't bother me providing support and service are good, and it's legitimate.
I would check with both Amazon and Lulu, but from both I've seen "updated versions" at a low cost, or free of charge to the original purchasers. I don't know how that works, though.
