I have the Defender series by otterbox. So far it seems pretty good. It feels more secure than the one for the EVO 4g. Its a little pricey at 49.00 but I think it will be a good case. Now that its out you should be able to Google it and get some reviews. I definitely like it, Rick.
I have the Otterbox Commuter. I do like it as it's very rugged but the rubber cover for the charger port tends to get in the way and the case is so thick that the kickstand doesn't work very well with the case on it. It's a great case, but I recommend getting the Defender as it remedies both these complaints and is even tougher.
I bought the purple Body Glove case at first and returned it because I just couldn't stand the fingerprints it showed all of the time. I exchanged it for the Otterbox Commuter case. I like it much better than the purple case and the Defender. It adds just the right amount of protection and not much bulk at all!! I am happy with it so far. I have not used the screen protector yet, I purchased the ones from Sprint and I am using one of those right now.
