Juicing

Anybody have a juicer?  I have been seeing a lot of posts on blogs lately of people talking about using juicers.  I have never had one and never really felt the need for it.  But I am starting to rethink this.  A delicious way to get a full days serving of fruits and veggies.  That's a win.  But having my kiddos drink it up and love it becuase it tastes good.  That's a win-win.  So here's my question.  Does anyone out there have a juicer and use it?  I have no idea where to find one that will really work like it's suppose to.  Plus, I have a feeling that they are crazy expensive. 

Any ideas or thoughts?  I would love to know what you think.
