Best Propellers for F450?

[cpercival]

So I can't seem to find Graupner 9x5 props anywhere (at least not stateside).
Who else makes a good propeller in this size? I don't mind doing minor balancing, but it seems like a quality prop shouldn't need much.
APC is a brand I see a lot, but they sound flimsy.
RCTimers sound like they're often horribly balanced.
Who else?

Hi again, cpercival,

My first build took off on its maiden voyage Sunday morning. It didn't crash. I did something right for once.

It's flying with Xoar beechwood wooden propellors. They're made in the US and they are expensive. You ought to be able to find them via a Google search. They were reputed to be quiet and they are. My craft emitted a windy wooshing sound but there was no electric-like buzzing sound heard in every video recorded while flying with plastic props. At this point I may never employ any other propeller. Xoar makes full size wooden propellors for small manned airplanes as well. A Chinese firm has already cloned them. Don't buy Chinese wooden propellors.
