Well, the E2 LCD grip is now being sold at PI. It can be found here:http://www.paintballinc.com/cgi-bin/paintballinc.filereader?3c9deff801b9ed5c2717d82a87 3a06eb+EN/products/04pief2
It is an SOB frame (just like the one on the E2). Although it's not too great an investment for someone that already owns a BD. It might be something for other Spyder owners that have upgraded their gun would like to have.
It's a great frame, but doesn't allow for sticky grip customizations and the trigger is made of a composite plastic material. Although strong, it's best to upgrade to a CheckitProducts Sweet Spot trigger to get optimal results from the electronic firing mechanism.
