Hugen has been developing further both the hardware and firmware of the edy555 design.
There are now many clones of what Hugen laid out.
I ordered a nanoVNA from Hugen's friend:
It arrived very quickly via DHL, included battery, cables, and calibration set, I am very pleased.
Here's the post where Hugen mentioned his friend:

Some might say that they all fail due to a flaky thumbswitch.
But you really don't need to use the thumbswitch much, the touchscreen is fine.
Do you really care about a 6 mo warranty on a $50 device?
I'm fine without, being able to immediately return a defective unit is
about all I could hope for on something like this.
Authorized distributor?
I'd say Hugen's friend, though perhaps there is a way to buy something from edy555 also.
The clones mostly work fine, but there have been some reports of bad workmanship,
no battery (understandable, some shipping services won't take a lithium battery),
no shielding (not clear that it really helps much), some may not work quite as well
at frequencies of 300 mhz and beyond, have older firmware installed,
no callibration kit, no cables, etc ...
