Which scholars are respected by Quranists?

Most of the information I find about Qur'an-only versions of Islam tend to be from some random webpage. Some examples are: - Quran-Islam.org . Some of the articles (possibly all) are attributed to someone known as "A. Muhammad". - Free-Minds.org . Some articles here are attributed to Layth Al-Shaiban who has a co-translation of the Qur'an (amazon.com ). - QuranMessage.com by Joseph A. Islam. Looking at random articles from these sites, aside from the Qur'an, the only references I found were to other pages on their respective sites; they don't even cite each other. It's hard to tell, therefore, which scholarly opinion Quranists value. **Question**: Which scholars are respected by Quranists?
