I think you scored a good gun at an awesome price friend. I do not know what your experience is with the 3rd gems, but if you started with a 39xx, now a 908, soon who knows what you will find next... I predict in the near future you may choose to change your forum name from Glockman to 3rd-gen-man!!! hahaha! just kidding! Just as a comparison, in my hometown here in Europe, there are two 908s for sale. 1 is described as "very good" at the equivalent of $596 while the other is in excellent condition and at $767. Two magazines each. I have no idea if they include boxes or not. To put prices in perspective, a rail P226 in excellent condition is $708, while a Walther PPQ 9mm in very good condition is $535.
Enjoy your new find friend!!!
