My copy is about worn out, used almost daily for about 10 years, less often for the past 20, with much editing of gendered pronouns. I also like Stern's gender sensitive updates, but not as well, because of unrelated changes that may follow the Hebrew more closely but seem to say the same thing less gracefully. This week, I bought two more recent Reform Jewish prayer books, "Mishkan T'filah for Travelers" and "Union Prayer Book, Sinai Edition, Revised." Love them both and can finally retire this lovely siddur.
