The Omega is by far the best. I'm actually saving to get one. ACME also made a great juicer that both my aunt and grandmother have. They've had theirs for over 10 years and the machines work GREAT. Both of these machines are easy to clean and have a powerful motor which will really get all the juice possible out of the veggies/fruit. You'll see by the amount of juice you get and the real dry pulp left behind.
At the moment I have a juice man jr. which works fine, but after six years of beating it up, it'll be dying very soon. At least that's what the noises it's making are telling me. :) hth and good luck. :)
