I absolutely love my Zenus leather case. It's a bit pricey at $45 after shipping but I love the grippiness and the card sleeve. I don't carry a wallet anymore! Just an ID and credit card. From now on it's going to be leather cases for me. It feels so much better to hold than a plastic case. It might not be as thick or shock resistant, but the extra grip definitely decreases the chance of dropping the phone.
If you don't want a card sleeve, maybe try the Pierre Cardin leather case (perhaps knockoff) on eBay for $14. I have no idea how that one feels, though.
