Which titanic movie would be my best bet?

I've spent the last hour trying to find the 1997 version of the
titanic movie in stores and I can't find it! So I finally decide to
try to buy it on Amazon.com even though I hate buying things online. I
was looking at the different ones I could buy and I wanted to know
which you thought would be my best choice and what you would
recommend.

There was: (The links I don't think are that important but are there
if you want to see the picture or prices to help me out more :) )

The regular titanic movie

Titanic 10th Anniversary Edition (I wasn't sure if that had anything
special about it or if its just the same as the regular one)

And a special addition (I wasn't sure if that special addition was
that good or worth paying more to get)

Help would be loved for those of you who have an opinion on which type
to get! :)
Also the Bluray addition will be coming out. I'm not sure how soon and
I really want the movie now, but would it be better to wait for the
Bluray addition? Especially because I have a bluray system?
