I have just broken my VNA, stood on it, look for a $40-$60 ones.
Ones to stay away from.
I appreciate your time.

Hi Alan,
Might as well get an H4. Bigger screen, SD slot, slightly better specs than the 2.8 inch units. Banggood has been shipping to Toronto in under 3 weeks lately and they're selling the H4 for just under $90. It will be worth it. 
Going for a $40-60 device will probably get you a noname clone. 
Black Friday is in a week, wait to see what the Nanos are selling for, then.

Maybe not!
It doesn’t show the Micro-SD card socket installed! Mine did about a year ago.

For $10 more you can get the SAA-2N, which has more-rugged type N connectors, goes to 3 GHz and has a sturdy steel case with pushbuttons instead of the push/jog switch. It comes with nice (rugged type N) calibration standards and a pair of fairly nice flexible N-male cables.

Alan,
I've had no issues with buying equipment from Banggood, with roughly 2 week shipping to Toronto. The SD slot may or may not be populated on the board but the pads are there. I installed my own SD card socket on my unit. 
I looked at R&L in Ohio. They sell the HE for $90US plus $30US for shipping to Canada  ($150CAD)  which I thought was exorbitant, so I ordered from BG and I'm very happy with what I have.

When you buy "clones" you never know what you get.
The first nano that I got, had completely wrong components
around the frontend and mixers.
After I replaced those with proper ones, there was not much
difference from the Hugen made ones, so there is some value
in buying the clones, if you are able to verify and correct the
mistakes.

If I may add my 5 cents worth here...

I have made many purchases from Banggood and AliExpress, if my purchase is
of mundane items, like connectors and such, I know that I am not going to
receive MilSpec items but they will be "good enough" for my use. I have
purchased some higher price items such as the Tinysa and the NanoVNA-F but
I buy from the official store as suggested by the Groups.io group Wiki page.

I find the trick to purchasing from China is to read the ad, ask yourself
pertinent questions, check the specs listed in the ad and above all, do not
read into the ad what isn't there.
One of the things that bug me is a seller will advertise a high priced item
for what is a good deal, show the picture of that high end item in the
lead-in ad and when you click on it the real ad shows the high end item yet
the description is for a lower end item, there are obviously different
rules for doing business in China than the rest of the world.

I even suspect that when an oscilloscope from a Chinese manufacturer with a
$500 price tag is offered at say $375 by an independent seller is actually
a quality department reject yet proforms good enough for someone like a
student or hobbyist

So I guess it comes down to caveat emptor, buyer beware.

I just purchased the -H4 from Banggood and to my surprise, it arrived at my door 5 days later (Ontario, Canada). My wife let me check it out just to make sure it's the real deal and then took it away for the Christmas wrap.... guess what she's getting me for Christmas?
 

Okay, so - you checked it out and????

Did it come with the SD card slot? What version of firmware? Did you open the housing to inspect the board?
