I think most of the home ones suffer the same problems. I don't have it, but I have been told by people who do the Williams Sonoma one is much less hassle than most of them. I have a cheap no name one and know it won't last long and I'm thinking about the Sonoma one.

Of course, if you have $700 to spend, there are some hand operated commercial ones that you won't have any troubles with at all. I keep hoping one of the used restaurant equipment stores will have it some day for a reasonable price.
