If I'm not mistaken the Brevilles are centrifugal juicers and that type is the least desireable cause they don't do well with leafy greens, soft fruits and they won't do wheat grass at all. The #1 choice are auger type juicers as they get the most from leafy greens,will do wheat grass and you can even use them to make nut butters. Short of a Norwalk Press they get the most and highest quality juice from all veggies. I have an older Omega 2003 and it does a great job but it's a bit slow. Omega just came out with a new design called the Vert that is getting very good reviews. Type "Omega Vert" on YouTube search engine and you'll see demos.
I can't even imagine not having citrus juicer when doing the MC. They can be had in the $10 to $15 range and besides making it much faster and easier you can get a lot more juice from the lemons and easily and it will pay for itself.
