OK, I know we've got the Rödelheim and the Adler machzorim which typically adhere to Western Ashkenazi minhag, but the former is prohibitively expensive and the latter appears to be out of print. Taking this into account, are there any western Ashkenaz machzorim which are still in print within an affordable price range?
This website gives the range of Koren machzorim including the ones with a commentary by Lord Rabbi Sacks. The blurb reads:
The Koren Sacks Rosh HaShana Mahzor and the Koren Sacks Yom Kippur Mahzor are a pair of Hebrew/English prayer books for the High Holidays with translation and commentary by Rabbi Jonathan Sacks, one of today's leading Jewish thinkers. The design of each book brings out the inner meaning of the High Holidays prayers by aligning the Hebrew and English texts, highlighting key words, distinguishing poetry from prose, and using beautiful fonts created by master typographer Eliyahu Koren. Rabbi Sacks’ translation brings readers closer than ever before to the authentic meaning of the Hebrew text, while his introduction and commentary provide new ways of understanding and experiencing the Yom Kippur service.
The nusach is related to the Routledge nusach and has זכרנו לַחַיִים (with a patach under the lamed) instead of the more usual זכרנו לְחַיִים (with a sheva - and according to the Tur and the Maharam Rothenberg).
The Artscroll machzorim can be found here .
There is a complete Western Ashkenazi siddur available for free online at the opensiddur site: the Tefiloh Sefas Yisroel, nusach of the now gone kehilla of Bad Homburg, a city near Frankfurt, Germany.
It was collated by Rav Rallis Wiesenthal based on pre-Haskalah manuscripts, with the assistance of Machon Moreshes Ashkenaz and Kehal Adas Yeshurun-Jerusalem. Online versions: XHTML, ODT, TXT and PDF. According to the site, one of the major motivations of making this siddur available is:
his hope that Ashkenazim (descendants of Rhineland Jewry) recover their historic communal and familial customs and traditions. Most descendants of European Jewry including Ḥasidim are descendants of Ashkenazi families ... The survival of these traditions largely depends on the Jews of Ashkenazi descent to honor and preserve these traditions.
Easiest thing would be to download the complete PDF file, print it out and bind it.
