I spent some time today talking to my contact there and I inquired about when the new models were coming out. He said that Cabelas and Basspro have the new 30' models and they have made many changes. The door seals have been changed, the chip loader is changed, there is an access plate on the back, and the element was changed to a higher wattage but can't remember what the old one or the new one is, but it is more watts. There may be more , just can't remember. The new 40' should hit the stores in January. Hope this helps.
