For my next build, I need a 2 1/4" three blade spinner.  I can find them with a bolt through the tip, but would prefer a bolt on spinner ( to backplate).

What's everyone using?

This is from ebay.  Spinners of all sizes, shapes, and materials.  Have cutouts for three blades, two blades or no cutouts.  Some have the screws/bolts in the front, others have screws on the sides.  I have found prices to be reasonable.  Shipping has been reasonably quick.
