Do any of you use a juicer for getting wheatgrass juice please? If so, what is your feedback on the one you have? I'm looking for an electrical one going at 60-80 rpm, wide mouthed (possibly for other fruits and veggies as well), must maximise *all* nutrients coming from home-grown wheatgrass and must be dead simple to use, and *very importantly*, very quick (under a minute) to clean and under £500.
