The Liturigia Horarum can be found in the Vatican. They have a 4 vol set with plastic cover but nice paper and print. It’s the LOH on the cheap and then there is the the deluxe set, 200 euro per volume. It’s a very beautiful set of books.
It’s been out of print for a while. I bought my set (plastic cover over which I put a leather cover) before that happened, back in the mid-2000s. The Midwest Theological Forum set appears to be the only one in print at the moment. I’ve considered buying it just to have a nicer set of books to work from but money is tight at the moment, and my Liturgia Horarum set (and self-made Nocturnale) work just fine.
I’m not a fan of the Breviarum Romanum. It’s a distinct break with tradition (almost as much as the Liturgy of the Hours), and as a Benedictine Oblate it doesn’t correspond to my traditions. I like the post-Vatican II version of the traditional Monastic Breviary (same schema as written by St. Benedict 1500 years ago), but it is way too long for lay use. When I do want to pray a monastic schema, I use our abbey’s breviary (monastic schema B). It is a post-Vatican II schema devised in the 1960s that is faithful to the Rule’s command to pray all 150 psalms in a week, but I still find it long (keeping in mind that I chant the hours and that more or less doubles the recitation time). Our abbey prays Lauds and Vespers in Latin Gregorian chant, the other hours (Vigils, Terce, Sext, None and Compline) in French with Latin hymn and Marian antiphon at Compline.
I’ll often use it for a full week at a time. Usually week III in the LOTH, as that is the week I dislike the most with very short Vespers psalms and very long mid-day psalms, almost as if mid-day is a major hour and Vespers a minor hour. I call them “Vesperettes” among my Gregorian friends

Since the monastic is a 1-week schema, I don’t miss any palms that way. I don’t use it in the summer though due to more hours spent with outdoor activities.
These days I’m a bit lazy and have been praying the Office of Readings silently in bed after Compline, and starting the day with Lauds. I need to shake that off and get back on my usual summer routine of Office of Readings combined with Lauds first thing in the morning (6 am). In winter I separate the two Offices, Vigils/Office of Readings at 5:30 or 6 am and Lauds at 7:30 am.
When does summer start and end? According to the Rule of St. Benedict on the Monday following the Octave of Easter until All-Saint’s. Our abbey ends it at the Holy Cross (Sept 14th). Summer ends sooner in Canada than Italy! In summer, the abbey omits the patristic reading and replaces it with a short bible reading (as allowed in the Rule).
