Didn't see this mentioned: There is a way to tell if you're dealing with a fake or genuine 82357B without having to do anything intrusive to the unit.
The inner metal shielding extends outside of the case, but only where the screws are at the back. This is only on the genuine unit, the fake unit is exclusively plastic. So if you see one for sale, this would be an easy way to tell if it's fake or not.

A picture of a genuine unit (notice the metal inner shield ).

It's hard to say with the low quality pictures, one had the cable replaced with the black USB cable, others look like they don't even have knurling on the finger screws and some even show some rust in that stack. It's a typical eBay auction of chance. The price alone says they probably are, but then again you would think that these should be dropping in price as people move to the new keysight meter as they discontinue the 34401A.
No way to confirm without better pictures, sorry.

Most likely fake because:
- I msg'ed the seller requesting more info / pictures and she replied with a nonsense response that would make you think that she doesn't understand English.
- 2nd picture having lower resolution than the 1st makes me think that the pictures are fake ( she does not have access to the items in the first two pictures ). I do think that the items in the first two pictures are genuine.
- The 3rd picture shows a single unit. This one looks different than the others. Notice that all the others have their cable tied with a zip tie. This one does not, it's cable it's tied with the same as the fake ones from other sellers. Also it's cable is folded neatly ( factory-packaged style ) vs the ones from the previous pictures where the cable is somewhat messy.

IMO the seller is posting pictures of used genuine units(to make buyers think that they are used but genuine) which she doesn't have and probably shipping out new fake units, as used.
But, you can make an offer asking specifically for the black cable one and only that one. If the seller accepts it's a high chance that you'll get a genuine one
