While you don't need any additional features when measuring beverages, I'd highly recommend the newest version, the H4. For working in the field the larger display is VERY nice.
I have one of the original, smaller nanovnas and its very difficult to read the screen outside. The larger screen is VERY much easier. And the price is about the same.
And yes, I've heard R&L has them and I think GigaParts is also selling them. Not sure which models.
Good luck
