I was in Singapore Wednesday. Didn't shop around too much as have caught a stomach bug somewhere in China (surprise) and combined with tooth abscess I didn't feel too well.
Without really trying, cheapest price for 10x42 Ultravids was Sg$1700-1750, 8x42's about Sg$50 less. Price varied enormously, as often the case, with first quote up to Sg$2250 or more. This was at Lucky Plaza (Orchard Rd).

I haven't checked Australian prices yet but this seems a lot less than prices quoted here, so ok if passing through Singapore.

Best wishes, Chris
