Australia is a rather small market with the extra burden of freight and GST. It is only to be expected that prices will be higher here, although sometimes they seem to be a bit over the top. I have bought a number of things mail order from the states, so far so good, but nothing requiring a warranty. It is worth spending the extra to obtain that warranty. Besides, our local dealers DO provide sponsorship and support for our astro societies and star parties
.,so they do deserve some sales. When ordering gear around the $1000 mark, have the packages opened, they can then be deemed "used" merchandise and lower the value by 20%.
