Expanding Mandrel

The Quick Release MT2 or between centers Expanding Mandrels offered by Arc Euro Trade (near the bottom of http://www.arceurotrade.co.uk/Catalogue/Expanding-Mandrels )
would seem perfect for some of my projects. Has anyone used these? What accuracy should I expect? Is there a North American source for similar mandrels with a better price/quality?
How is Arc Euro for shipping to Canada?
