I'm looking to use it for HF/VHF/UHF and can't really tell which are actually different or better or which features are fake seller marketing hype. Eg., "Latest Upgrade!". Is it really?

Not sure how much I need to spend to get the results I need.

(I did a search of the group for "NanoVNA" before asking in this post, but the different discussions didn't really clear up the issue for me.)
