I use the Seidio skin / holster and love it. Was worth the money to me. Droped my phone on the street and it didnt even scratch the skin. It just paid for it self right there for me.
Does your skin have a screen protector? I don't really see the point in a skin unless it protects the screen like the iskin's for ipods. How much can you really mess up with batter cover and keyboard?
hey i have the 8300 curve leather case as well as a bold case for my skinned 8900 (i found these two cases pretty much brand new in train i take to school LOL) but yeah the BOTH cases fit my phone but the 8300 is a BIT snug and the BOLD is a BIT loose so take ur pick!
personally, i like the BOLD case better, it gives me a little bit of wiggle room and easier to take out while holstered on my belt and the stand-by magnet works better as well! i hope that helped u a little bit =)
