I hope you folk in the USA realize how lucky you are to have so many paper choices available. I will definitely explore the US-only options, such as InkjetArt and Hawk Mountain, if the options available locally pan out, so thanks to those of you who took the time to recommend them. I can ship them up, it's just that there is an added charge for brokering on top of international shipping, and of course returning a defective box would be a hassle.
Neil: HP Satin is available here, so I will give that a try - thanks.
Tim: I had to laugh: CCBC's house luster (rebadged Premier Art?) is what I use for all my draft work. The price is definitely right! If it weren't so darned white I'd use it for final prints as well. Not only is the pure white too glaring in the margins for my tastes, but as the OBAs fade it yellows (prints from 3 or 4 years ago show this), so I'd rather compensate for the yellowing up front, rather than have a colour cast spoil the image down the road.
