Acme taps for the sizes used in machine lead screws are hard to come by, and if you find someone who sells them they tend to be REALLY expensive.
I found this store on ebay, they are UK based but also ship internationally. I'm in no way associated with them, just a satisfied customer.

There prices are very reasonable (much cheaper than most suppliers) and they have many hard to find Acme taps even left hand thread.
Hope this helps!
