I've compiled this list of reviews of AGD products from various websites. Feel free to add any others you may find.
However, I did intentionally omit 'amateur' reviews from such sites as pbreview.com, as the quality and objectiveness of these type of reviews varies greatly. So please refrain from posting links to those type of reviews.
