Those ones from Ikea consisting of an oval plastic bowl with a grater lid plus a plastic one. I've never grated my fingers on it, plus then you have a handy bowl with a lid if you've grated too much, innit.
yes, I use a mouli-legumes. I don't know an English word for it. The cheap ones are tinplate and go rusty, oddly the plastic ones are better, provided thet have stainless-steel drums. You ought to get a few interchangable drums with different size teeth. They are easy to clean with a nylon washing-up brush, the trick is to clean teh drum mostly from the inside. Dishwasher will do it anyway.
I would recommend a good barrel type grater. Pampered Chef sell a fantastic one. You could also buy their microplane which has a special hand guard to ensure you get the last of anything. Both work on chocolate, cheese, nuts, ginger etc.
If you don't have a consultant, let me know and I can give you my web address.
