Need help in purchasing the right case for me

[jsoni413]

Hello all. I have been using the Elago s4 for a while, loved the slim design and feel in my hand. This past weekend it was dropped and the front screen was completely cracked. Clearly the Elago s4 has no front-screen protection. I needed some advice on finding a solid case that won't add TOO much bulk, but will offer solid drop protection for both the FRONT and BACK. After browsing this forum I have found that a few solid options could be the Magpul Field Case, Speck Pixel HD, and the Otterbox Commuter. Just need some opinions from people who have these cases or any others on which could fit my need for a solid protective case without too much bulk added, as I do appreciate the slim and sleekness of the device. Thank you.
