Geez - from the title I thought this would be a primer on dating and marriage.....
I am not sold on the electric versions. I still have an old mechanical hand cranked version with an attachment that fits over the output for stuffing sausages, and it offers better control (especially if you happen to be sausage stuffing with your mate, and you know what they say, the couple that....well never mind).
I also like the way the old mechanical grinders break down for cleaning - quick and easy - better than many electric grinders.
I guess electric meat grinders are right up there with elkectric knives and electric pepper grinders - sure, they work, but aside from a few limited functions (the electric knife can cut jelly like foods without squashing them), I just don't see the point in all this new-fangled frippery.
