There is only one way to get it just like you want it.. Build it yourself <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
Seriously, I find the prices in Aus good. You want to buy the sail from a sailmaker who knows the boats, rigs and sailing techniques. You probably also want him to tailor it somewhat for your conditions. This means you can not just go to any sailmaker and expect a good sail. I dont know any sailmakers who qualify in the far east, but there are several in Aus and the US.
What is Ashby charging for an F-16 main these days? Glaser lists US$1300 on his site for a main, but I dont know how current that price is. Landenbergers site is just re-done and dont list F-16 sails at all.
