I''ve read a bunch on 10 or so vendors that are discussed often in here, which would make me very comfortable buying with many of them. I''m just wondering why some of the other ones like Blue Nile/Mondera aren''t discussed much. I assume it is because the general feeling is that their prices are higher, correct? What about service? Also, using Blue Nile as an example again, that one never comes up in any of my searches on pricescope? Why? I''m just trying to compare everything and understand why some of these other sites/stores aren''t discussed much. Thanks...Brian
