Recommend: Sand Sifter/Stirrer

I'd avoid sandsifting starfish altogether. As others have posted, they eat all the life in the sand bed. Nassarius snails do a decent job. If you really want to see a sand bed get turned over, get a convict blenny. I have 4 in my 125 gallon with a deep sand bed, and they turn the sand over a lot. Take a look at some pictures of the adults. Other than their head, they are very eel like, but without the issues of eating small items, and being escape artists.
