All:

Du-Bro has very good plastic spinners, always well balanced, and sturdy enough for using an electric starter.

Other plastics range fron "Wouldn't have it on a toy" to acceptable, but I'll stay with the Du-Bro for my plastics.

In metal, I've not seen any that were not OK. I've used the SpinRite from Maxx porducts with good results, but they always are out of balance.

My favorite, of course, is TruTurn. Have several of them also.

But the aluminum backplate with the plastic cone I do not like, not because of weakness or any design fault, I just don't like the looks.

Bill.
