I have a Sena case for my HP 1945 and I absolutely love it.
I really looked around this time before buying a case as I'd come to realize what a crucial accessory it really is.
I was prepared to purchase a really high dollar one from Piel Frama (they have beautiful cases if money is no object), and I read about Sena in a magazine.
The color selection is great and you can select it with or without a belt clip.
I highly recommend them.
