Well zack Attack wheatgrass is a juice that requires a mastication juicer.I use a greenster2000 to juice the barley/wheatgrass that I grow during the spring and summer months.The grass juices are expensive and difficult to grow.Not to mention labor intensive!I have a coupple of pictures at ewheatgrass.com under jj43.I have never made orange juice do to the fact I like to eat oranges.But as a general rule of thumb mastication juicers dont do soft fruit well.My first juicer was a juiceman juinior that I purchased at walmart.A centrifical juicer is a good first juicer from an ease of use pont of view.Good luck and happy juiceing!
