I'm looking to get an battery booster. And I'm torn between these 3 battery packs. I'm looking for one that works, and fits with my case on it. http://www.monoprice.com/products/p..._id=1083110&p_id=5480&seq=1&format=4#feedback http://www.amazon.com/Miccus-CMC608...?ie=UTF8&s=electronics&qid=1259609100&sr=8-37 http://www.amazon.com/4400mAh-Exter...dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 Any suggestions, thoughts, etc. Would be appreciated.
