M3 Tap for Durga

[Zipper]

Hi,

After reading through the review & the threads on here, I want to tap the holes before I start building.

Where's the best place to purchase one, i used modelfixings before but they are all out of M3 taps. Can anyone point me in the right direction for an someone that stocks a M3 tap?

I have found this tap on ebay; M3 x 0.5 - is this the right one?

Thanks!
