I have a non rotating ss spray thing, it's rubbish, I also have a cheapo mister thing, never got it to work right.
After holding out for cheaper SS rotating I gave in and reluctantly got a plastic one (careful-easy damage to threads)

Its works great, dogs dangles even, although I do have a ridiculously large CIP pump that can spin the thing into orbit as the std march brew pumps etc can't raise the necessary pressure.
Must stop looking at conical threads ($$$$).. I'm going back to smaller batches and reusing Dolium or other kegs as fermenters for ales .......... just replace every so often
