One of the most popular and recommended locations to buy an iPad screen cover is Best Buy. Not only to they have a wide variety of this product, they also offer a warranty on most of their products.
The Smart Cover designed for the new iPad2 is the same size as the original iPad because the two iPads have the same size display. However, the Smart Cover is attached to the iPad 2 by magnets. The iPad 2 has magnets inside and so does the Smart Cover, there are 21 inside the iPad 2 and 10 more in the Smart Cover. However the original iPad has no magnets so there is no way to attach the Smart Cover to the original iPad. Some of the magnets play another role, the Smart Cover can wake and sleep the iPad 2 by opening and closing the cover. This is also done with some of the magnets. I would not try to use the Smart Cover on the iPad, it was not designed for that purpose and would be a poor substitute for a cover better intended for that purpose. Dah•veed Monterrey, Mexico
