They have range of stuff; the cheapest is their Leaf 2 - €240 which is 350 CAD or £210. But yes it is more expensive than Kobo and Amazon; I try to remember they subsidise their ebook readers as they want to lock you in to their stores, and the Boox is more versatile as an Android e-ink device. I haven't used the Leaf 2 myself, but the reviews I've found sound like it's a pretty good ereader.
If not interested in e-ink, then any good generic Android tablet beats out Kobo and Kindle devices for freedom and are comparable in price.
