You really don’t need a missal to attend an EF mass. All of the masses I have attended have a booklet missal with the ordinary of the mass and some of them also have a bulletin with the propers for that Sunday’s mass.
If you think you will be attending the EF regularly and really want a missal, I have the New Roman Missal by Father Lasance which has the English and the Latin the same size and not with the Latin “squished” as in the Baronius. You can get it on-line from:
moscompany.com/catalogs/catalog.asp?prodid=1419619&showprevnext=1
and I think Leaflet Missal Company also carries it on-line and their shipping is really fast.
The readings are a bit different because this missal does not have the changes instituted in the 1950’s. I have also seen the New Marian Missal and the St. Andrew’s Missal are available on-line, but I don’t know the size of their type.
