Where to buy local?

[kidvdub]

Hey all,

I just posted a few threads but am a very active member in the "car enthusists" forums......(cant tell by the screen name).

Anyways, I live in the Los Angeles area and would like to find local stores that carry accessories for the Treo 650.

What I am looking for is a car charger (not sprint or radio Shack), USB sync cable and a head phone adaptor not sure if I need one or can a head set plug into the phone with out it?

ANY help is greatly appreciated.....

thanks
