What Fitbit should I buy if I want something simple and thin?

I was looking at the Inspire 3, but do not love the design (it is okay). I had an Alta, but I did not use it for like five years and it died. I liked that design since it was just one straight-line shape and did not have excessive amounts of feature. I would rather not have distractions on my wrist in addition to my phone (which is why I am not getting an Apple Watch). Would a used Alta make sense?

I personally love the streamline look of the Inspire 3, but if I had another choice, I would definitely buy a used Alta. If you like the look and that it works better for you, I would say go right ahead and buy a used Alta.

@CatholicPuppy Thank you for your insights. 

@jayadb3 A warm welcome to the Community! Thank you for your message. Depending on your needs and according to your description. 

You could have a look at the Luxe or Inspire 3 if you want a colored display. If you rather have a bi color display, the Inspire 2 could be an option. 
Those are the current trackers in a long , slim format.
