After watching your video, I had to go to ebay to see what is available for a juicer that works like yours does. There's a few hand crank types that have the same mechanism as your electric one. I'm going to have to order one of those, it'll be faster than the simple one that I have right now. :-)
There are some great juicers out there, even a few that are electric. The electric ones can be a little expensive, around $100 when I last looked. but they really speed up the process if you have a lot of tomatoes to process. What variety of tomatoes do you grow?
