What Fitbit products record EOV?

That's all I care about. Whats the cheapest watch that will show me maximum sleep details and show a graph like this. I need to see Oxygen saturation & Heart rate. Thank you.

All Fitbit watches currently available do that. The cheapest is Inspire 3.

@Dopovo Thanks for your input.

@TheEgg Thanks for reaching out about EOV (Estimated Oxygen Variation). As mentioned above by Dopovo, all Fitbit devices currently available record EOV. The device with the lowest price is the Fitbit Inspire 3. More about this device you can find in this website: FAQ - Fitbit Inspire 3.

I actually made a mistake: Fitbit ACE 3 doesn't measure EOV. 

I'm not sure why @RodrigoMFitbit you fell the need to comment adding practically nothing to my post.

@TheEgg  You mention oxygen saturation in your post.  I need to point out that this graph is NOT showing your SpO2 measurement.  SpO2 is a "%" number.  Please notice how the y-axis has Small and Big, with no numbers.  The current graph says Low and High, with no numbers.  IMO, Fitbit put an interesting spin on why there are no numbers.  Fitbit released the EOV graph in Nov 2019.  Fitbit didn't start reporting average sleeping SpO2, meaning it didn't give users a --%, until Oct 2020.  Fitbit didn't get FDA approval to report SpO2 % until Oct 2020.

If you are looking for a true sleeping SpO2 graph, the EOV graph is not it.  No Fitbit gives you a true sleeping SpO2 graph.
