I was all ready to order a new Doiron M2 handpiece to fit my flex shaft unit from Brownells and now see that they have discontinued selling the unit. Does anyone have a suggestion on a company or place to order from or maybe someone has a M2 handpiece they want to sell for a reasonable price?

Thanks Duane, thought I was going to draw a blank there!
