I found the cheapest 8830 holster here at Amazon.  Since I've never seen an actual holster for the 8830, I didn't really know what to expect.  Because of the low price I paid for it, I thought I was buying an aftermarket replica.  When I received the holster, my suspicion was confirmed, so I thought, because it didn't match the picture online.  But soon, I was able to compare it to my brother-in-law's holster which came directly from the RIM online store.  I was happy to find out that they are exactly the same.  He couldn't believe the price I paid for mine.  BTW, the picture shows stitching that runs in front of the holster.  The one for the 8830 doesn't have one.  Anyway, the holster is very well made and my 8830 fits perfectly.  One thing I'd like to mention is that using one of those silicone skins will make it a tighter fit.  I was told it would fit without any problems but that's another review for that item.
