I was wondering if there is a 'Minhag Ashkenaz' siddur presently in print. I have an older one at home, but it has sentimental value and as a university student, I would rather avoid using such a siddur on campus. I typically use a Siddur Rinat Yisrael, but tachanun and birchot hashachar are different from the German variant.
I have been compiling a German siddur for the past fifteen years. It is currently available on www.thebookpatch.com:
This 2011 link to the Siddur Tefillas Yeshurun metioned by yitznewton may be valuable to sign up for the new edition. You can also contact www.kayj.net
You ask for printed editions. The following are available online. You could print what you wanted I suppose.
- A Category at the Wikimedia Commons for scanned works of Wolf Heidenheim, including a full set of mahzorim and many editions of his siddur: http://commons.wikimedia.org/wiki/Category:Wolf_Heidenheim
- A Category at the Wikimedia Commons for scanned works of Seligman Baer, including two scans of Avodat Yisrael and one of Kinnot: http://commons.wikimedia.org/wiki/Category:Seligman_Baer
Siddur Sfat Emet (known as the Rödelheim siddur) is in-print and available for sale here: http://www.booksnbagels.com/eng/productinfo.php?id=9708
I have a copy of the OOP 1st ed, second is in prep
If you are still looking for a German Siddur, the siddur of Rav. Hirsch is probably the best option. It is in the style of Minhag Frankfurt, which is more of the Ashkenaz minhag than Siddurs from Northern Germany.
