Thoughts:  If the Mass is full of you, your instead of thee and thou, it has been modernized.  I don't want that myself.  St. Joseph may be mentioned as one of the saints in the Canon, that is a tampering that is not allowed.  Also, the most important is the rite of Easter.  The new and revised will say if it has been messed with and if so, it was taken out, many pages.  It is not a messing with, but a destruction.  Those are the tell tale signs.

The Best is the St. Andrews, by far!  Cost is high, but you will have no regrets buying it.  My husband has one and he just can't get over all that is in it and things he never knew that are explained through  out the missal.
