That's going to end up around 900 bucks probably, and when it does, it's no longer a good deal. The only one that's worth anything is the M4-A1 with the Crane stock, as it as the new electronics package. The earlier PTW models had problems recognizing the reseating a loaded mag, and the release of the bolt, so on and so forth.
While they are cool, the transition costs (mags, gun, upgrades, and so forth) are too high for what the current tech is right now.
