Hi Bill,
If you are after any left hand acme taps, I have put a few people onto the RDG ones in the UK and they have been happy with the taps and the price. One guy in the US had 2 x 5/8 (I think) taps sent to him and it only cost $55 US, which was half the price he could get them from over their. They have a few sizes.

If you sign up to the RDG website (don't need and credit card info) it will show you the shipping price if you add it to the cart. After looking you can just delete it if you don't want it.
