What is the best manual lemon juice extractor/press.?

I like making home-made lemonade at home. And I haven't really found a good fast way yet to extract lemon juice. The twist jars take a good amount of time and the screen gets full of pulp and is hard to clean. The Mexican style hand juicers that you squeeze like a set of pliers don't work very well for me (they don't get much juice out) and I've even broken a pair. So far about the best way has been a wooden hand juicer over a wire mesh screen and a bowl, but that takes a while.

So I got thinking about how the lemon shake up stands normally juice lemons with those presses where you put the cup under the press and pull the lever down. Since they are so expensive I'd like to get the opinion of someone who's ran a lemon shake-up stand on what brand they most recommend. I figure if it can handle that kind of use then it will work for my home use without breaking down.

If you've ran a food stand and served lemon shake-ups, can you recommend what brands are best to buy. THANKS!!!
