I also have the Cabelas 11 lb version. Got it about 4 years ago. Mine has teeth on the shaft all the way to the tip. Newer ones have the teeth machined off for some reason--maybe to prevent us from jambing the plunger into the bottom and breaking the gears/teeth.
I wish I had the larger model. I generally do 15 lb batches of brats or summer sausage. Would be nice to load it with the whole batch and stuff. But they do get pricey fast above the small model.
Sausagemaker sells some good ones too. Not sure if they are any better than the Northern Tool or LEM.
The flat bottomed meat containers on the LEM, Northern Tool, Sausagemaker are nice because they will stand up by themselves on the counter as you refill them.
The Cabelas has the spout coming out the bottom at an angle, so it will not standup by itself.
Look at the websites, go to stores that have them in stock--Northern Tool, Bass Pro for LEM, etc. And surf/search Google. Then buy the biggest one you can afford, because you will wish it held a bigger batch.
