I LOVE LOVE LOVE the Olfa frosted rulers!!
Here's a link to the US site:

I don't need a TON of rulers because I make 90% of my cuts with the Quilt Cut2 - again, here's a link:

I have a 1" x 6" ruler I also use quite often.
Enjoy your trip to the US and be sure to stock up. When I lived in Bali and Panama, it was extremely difficult to find much of anything of any quality.
