HELP!!! Tudor Submariner or Rolex Submariner?

[The Laird]

Hi Everyone,

As I have a very limited watch budget, but very much like the Rolex Submariner's, but find them still too pricey for my budget; I was wondering about the Tudor Submariner's?
I often see these for sale at a good price.
I am talking about the earlier Tudor Submariner's, which I believe are just the same as the Rolex one, but with a different movement? Again, I believe an ETA movement?

What are your opinions on the Tudor Submariner's and do you think they are a good alternative to the Rolex Submariner?

Or, is it a case of; a Rolex by any other name, is still a Rolex?

Many, many, many thanks in advance.

Till next time...
