We have an Omega and my DH uses it every morning for fresh juice. He also uses it to make nut butters and even nut flours.
It all depends on what you expect out of it. If you just want juice, buy a cheaper one. If you want the option of making your own nut butters, pasta, grind coffee and spices, look at the Omega's. We found ours online for $179 (with a coupon) and free shipping. It was a steal!
