Encased Rebel, Caseology Parallax, and the CaseBorne V (aka Armadillotek). The CaseBorne is probably what I'll use long term and it's the most protective but it's a little bulky and you have to be careful to put it on correctly: take out the plastic front frame/rim piece and put that on the phone first, then put the rubberized back onto the phone carefully fitting it over phone+front frame (it's hard but doable).
