To the O.P.
If you are interested in an Eastern prayer rope/chotki/vervitsa/komvoskini (they’re all the same thing) that is made by a Catholic, I make and sell them.

I would be happy to provide you with a 33, 50, or 100 knot rope. If you’d like to send me a message I’ll let you know my prices.
As for your second question, don’t consider becoming an Eastern Catholic unless you’ve been attending the Divine Liturgy regularly for about two years. If you haven’t been most bishops will not take your intention to switch seriously. The more you attend an Eastern Catholic parish, the more you will realize that we are very VERY different from Roman Catholicism in liturgy, theology, spirituality, mentality, etc. So attend a parish for a good period of time first, get used to us, see if you are comfortable being with us and feel more at home with us than where you currently find yourself. There is no need to switch sui iuris Church to attend the liturgies of another Catholic Church.
If you do eventually become and Eastern Catholic, you could still pray the Roman Liturgy of the Hours and even attend daily Mass at a Roman Church (most Byzantine parishes do not have daily Liturgy). I would ask why you plan on switching if you wish to continue these practices, however. The East does have its own Liturgy of the Hours, but it is never celebrated privately. One may pray excerpts of it privately, but the Hours as a whole usually are only celebrated by the parish gathered together. If you’d like to get a taste of what our Liturgy of the Hours looks like, I’d recommend checking out an Horologion from Sophia Press available from the Melkite Greek Catholic Eparchy of Newton -
www.melkite.org . This, however, will only give you a rough idea because it consists only of the “fixed” parts of the Liturgy of the Hours and not the variable parts taken from the books for the feast of the day, or for the Tone of the week, etc.
One way or another I wish you the best of luck. As one who has made the journey from West to East I can tell you that it is a very rewarding one, although it does force one to broaden one’s perspective on the Church.
