I have a the St. Ambrose PB, the Book of Common Prayer published by Lancelot Andrewes Press, and also a digital copy of the St. Andrew Service book.
The St. Ambrose book contains private devotions for morning and evening, devotions for mass, the text of the Masses of St. Gregory and St. Tikhon, Rosary instructions, prayers to the Trinity, to the Holy Spirit, and to the "Sacred Heart." It also has devotions for Eucharistic adoration. These last two might be controversial to many Orthodox (including to me).
The BCP is essentially an Orthodoxified 1928 BCP, with selections of the daily office, the Liturgy of St. Tikhon, the Coverdale Psalter, and a selection of variable parts of the Mass. The Feast of the Sacred Heart is included, with some other post-schism feasts and the rite of benediction of the Blessed Sacrament. Physically, it's beautiful.
The St. Andrew's book if official for the Antiochian jurisdiction I believe. It's like a BCP, but leaves much desired. It also includes eucharistic devotions.
