I picked up a 5lb LEM vertical stuffer with metal gears and sausage kits for $149 at a store called Fleet Farm in Minneapolis, but it wasn't on sale. I do recommend the kit though. It is a good solid stuffer. It was around the same price as the stuffer Gander Mountain sells but Gander Mountain doesn't have metal gears and didn't come with sausage kits. I recommend looking for a the LEM unit online if you are looking for a sale.
I did just find out that this doesn't come with a tube small enough to do sheep casings for breakfast sausage. That is $13 more from the LEM site. (I hadn't tried the small sausages yet.) the small tube is metal. It is still a fantastic stuffer.
The LEM 5lb stuffers are out of stock and backorder pretty much everywhere. I just ended up ordering a Kitchner stuffer (was $99), about 30-40$ cheaper but with plastic gears.
