I recently got interested in ordering some Edmund Optics RKE eyepieces. As a purists minimal element eyepiece, they seem to get very good reviews, and are supposed to have "excellent" light transmission. One such review (for planets) is:

So, I proceeded to the Edmund Optics website to look into them, including the price. When I was first checking out the prices of the Edmund RKEs, they came up as $85 each, but when I changed the country to Australia (top right hand side of Edmund Optics website), the price jumped to $137.70 each! I was quite puzzled about why the price should be so much higher for Australia. Then, after I was contacted by Edmund Optics Singapore who are the sales support for Asia-Pacific, including Australia, they informed me that the higher prices are in "Singapore Dollars", not Australian Dollars. So, the $137.70 is really only AU$108. And there is a possibility that they could provide a quote with an even cheaper price that may bring them down below $100 each! Now that looked much better to me!
So, I decided to order all of the 1.25" RKE eyepieces (8mm, 12mm,15mm, 21mm, 28mm) but decided against the 2" 32mm RKE Wide-Angle, which was well over $300. I also added a few rubber eyeguards, 2" and 1.25", as I believe they are not easy to get elsewhere.
The price to Australia, being in "Singapore Dollars" is not at all made clear on the Edmund Optics website. So, I hope that this information helps others when deciding if they should order these eyepieces.
