These are both dead links, as they are products that have not withstood the test of time. I would recomend the 800JEXL, by Breville. This is their Elite model that boasts 1000-watts of pure juicing power. If you are patient I would recomend another model, however if you desire efficiency and speed then this baby will make 8oz of juice in about 5 seconds.
If you are looking for a cold press jucier (a.k.a. masticating juicer) you are welcome at http://bestpressjuicers.com/. There are a lot of decent reviews, so you can pick a juicer which match your needs.
Omega J8003 Masticating Juicer is the best juicer.
Why do I LOVE the Omega J8003 juicer?
Three simple reasons:
1) It’s affordable($206.99)
2) It’s a slow-press masticating juicer that makes high quality juice and can easily juice wheatgrass & greens too
3) It’s easy to clean and re-assemble
I will recommend you buy masticating juicer instead of a twin gear juicer. One of the best things about them is that they are affordable juicers. You don't need to pay a huge amount to buy this juicer. All masticating juicers give a more nutritious juice by breaking down the fiber of the fruit and vegetables more thoroughly, releasing more nutrients into the juice
