Spacecraft Films DVDs - other space related DVDs

Hi All,

I am trying to acquire as many space/astronomy related DVDs I can find.

I have noticed a company called Spacecraft Films offers some pretty
impressive looking DVD packages.

Has anyone purchased these that would like to comment on them. How do they
compare to others?

Thanks

must haves that I am missing, please reply too:
