Roy,
I have had one of the hand crank units for many years. It was my grand parents and has seen a lot of use. It isn't bad cranking the thing and it works like a champ.
I also have the meat grinder attachment for my Bosch. It is all metal and has never let me down. But when I have a lot to do I use the old hand crank model. It reminds me of my grandparents and the times we worked to make Italian Sausage for the hollidays.
By the way, don't you have a son that needs to be taught the finer points of meat grinding and sausage making? I got to crank and add spices when I was a boy. Think I'll pass on the tradition to my son

.
The extra money could mean a few more fishing/hunting trips. Alaska air has some real deals to Alaska if you buy before the 28th and you don't have to use them till sometime in June.
Hope you find what you are looking for. If you want to try my grinder let me know,
Ray
