I know you said you want a keyboard case, but do give the Samsung Book Case a look. B&H has it for $50. I used their ad to price match at Best Buy. After using several cases on my iPads, including the smart cover and several cheap iterations I can say that this is the nicest case I've used on a tablet. The mounting points on the back of the Tab S make for a very positive attachment, and the magnets on the fold hold the easel positions far better than the iPad's cover ever did. I also like the way it wraps around- it makes it more secure and it doesn't open in my bag. (can't say how many times I found my iPad battery dead because of that). I got used to the smart cover on the iPad and was afraid I would have to give up turning the tablet off by closing the case, but this one does the job perfectly.
