Hi Buddy!

Executive Products Inc. sells a leather case for the Stream2. Granted, it
isn't silicon, but it offers better protection if used conscientiously
compared to the flimsy thing that comes in the box. It includes a zipper
pocket on the front flap that can cover all the keys when you don't want
them exposed. 

It also includes a covered belt clip. You can get it cheaper directly from
them, or if it is more convenient, I can organise it for you. Just contact
me off list if you prefer that service.

Hope this is of some help.

73,
Dave
