Portal 2 Turret Finally Comes Out Immediately Sold Out

The Portal 2 Turret I wrote of about a year and a half ago from Gaming Heads, that was last seen at NY Toy Fair 2011, not 2012, suddenly came out and immediately was sold out. Sure the regular edition is still avalaible, bu the limited edition with sound effects or the good model, which is only $30 more is gone.

Gaming Head seems like a unrelaible company from this endeavor as there should be one model of Portal turret to get with sound and a lot more for people to purchase. The inferior model is a joke, who wouldn't want sound for $30 more. Then the time it took for it to come out with no real announcements? Companies that don't treat customers fairly like Gaming Head should fail.
