Excelsis - a web site that posts reviews astronomy equipment (as well as many other items not related to astronomy). The reviewers are folks like you and me who simply hit that Web site and add a review, so you don�t have any way of determining the skill or experience of any particular reviewer and often the reviewers don�t mention how they are using the equipment they reviewed. (For example, an eyepiece may have a great field of view, but if used for high magnification you want to know more about its contrast.) Nevertheless the reviews are worth perusing.
