You need to research belt clips because those cases are beautiful. I'm purchasing the Tour next month and would seriously consider buying one if it had a belt clip.
Whatever you do don't succumb to this
thing like Vaja did. Or this one -

I think a swan neck clip covered with matching leather would be great because the "swivel" feature is so overrated.
The best handmade case and belt clip I've seen is by a company called Orbino but they are obsessed with Apple products only.
Then there's Nutshell. They have a great belt clip - long, flat, doesn't dig into your crawl, but the case itself if kind of uneventful.
About Belt Cases
I've yet to see one leather case manufacturer pull it all together and create the perfect product, so there is a niche. But don't let the clip be a secondary thought or you'll fall into the same pot as the rest of them.
