Looking for a wallet size/style case for my Treo 650.

I saw a few on Ebay but not what I am really looking for.

I am looking for:

- Leather case
- A small/thin case where the Treo is on one side and a place/slot for a small notepad on the other side
- Do not want any belt clip thingie, but something that would slip inside my suit jacket and/or back pocket. A simple case that folds similar to a wallet.
- Not looking for a case that is functional to allow camera usage or the like

And/or if not specific for a Treo 650, possible suggestions for a PDA general type case as I seek.

Thank you
