Where to find a k-5iis in L.A.?

Depends on how far you want to drive.  A one to 1.5 hr drive from LA allow you to touch a lot of Pentax gear.  The Ritz Camera Store in Riverside, California was bought out by a NJ based store and has a good selection of Pentax gear including the K5iis.  They are closed on Saturdays, but open the rest of the week.  I dropped in today and they even had a Pentax rep there.   I have attached a photo of their display.  My apologies posting an IPAD camera image on a Pentax forum, but at least the subject is Pentax cameras.  Once you come to Riverside to buy your new Pentax gear during the holidays, you can try it out by coming to downtown Riverside

to the Historic Mission Inn and photograph it's 2 million lights.
