I'm thinking of investing in one of these. Two seem to be available on-line. The cheaper, unbranded one, is green and costs around £30 from Amazon etc. The other is a Clarke one, costing around £40. The on-line reviews seem to agree that the cheaper model is a bit flimsy so I'm leaning towards the Clarke one. I can't find one locally so will probably have to mail-order it. I want it to sieve my home made compost, which I currently have to do with a hand sieve (or riddle as my Dad calls them). This is very boring and time-consuming not to mention ache inducing. So I'm looking to the rotary one to be quicker and easier to use. Any information gratefully received.
