Broken MM Bit

[Flynnster]

Hey guys,
Snapped off the bit on my MM Cob the other day, it had a crack in it. Not sure what from but I'm not exactly gentle with them.

Any particular replacement I should use? I know I can get the MM ones for about a buck, but always up to new options!

Or if anyone has an extra laying around I'd love to buy it from you!
