I'm a big fan of the switcheasy canvas case – the specific new iPad version.
Great design, highly functional and very good workmanship and materials.
Do a quick search and you'll see a big thread on them with many, many people very happy.
There were some issues with the magnets (like many case manufacturers encountered) but that's all been resolved and all the new cases sold from them are totally functional.
I would also highly recommend ordering directly from switcheasy.com as they offer a great warrantee and will get it you super quick.
Good luck on your search!
