I've got Decker's Greek reader in dead tree format, and really appreciate it as a way of keeping my Greek current (as a supplement to reading Scripture, not a replacement before anyone jumps on that!)
It has links to books like Wallace's Greek Grammar Beyond the Basics and a number of other grammars and lexicons that I have in Logos, so would be a much more useful resource if it were available in Logos format. With the links to various grammars and so on, it would probably enable Logos to sell more of them as well. I know it's often recommended (that's how I ended up buying it)so am sure it would be a steady seller for Logos.
