Where can i find the best case for samsung strive?

i bought a pink hard rubber case off of amazon about six months ago. it lasted for about two weeks. during those two weeks though, it began shattering (as in, i would look down at pieces of the rubber would have fallen off). my mom has an otterbox for her blackberry torch and its amazing. unfortunately however, otterbox does not make a case for my style phone. :( i just need a good case (i would like it to be silicone so that it won't break) thanks!
