[Treo] Centro and belt holders

[bearcatrp]

Looking for a pouch/holder (whatever you call them) that my centro can 
slide into while attached to my belt. I hate the swivel clips but 
everything I find has a swivel clip. Anyone know of a good belt holder 
without a swivel clip? Thought about a small pouch (used for small 
cameras) and a D ring to attatch to my belt loop but to much swinging 
around. Suggestions?
