I too found myself in your position last year. I believe I put up a post too, similar to yours. I stalked royalenfields.com for months before I found my bike on said site last May. I got damn lucky, I believe. I was pretty specific with what I was looking for, iron barrel, right shift, black. Got all that with electric ignition and a disk brake. I couldn't be happier. 2000k miles in, no problems really. Dumped the hump, new chain and sprocket, new clutch, I'm learning and I love it!
That said, agent x is right, what you are looking for just might not exist. I was prepared to buy outside of where I live (new York) and you should be too. Do you have friends that live in other places that could scope a bike for you? Widen your range. Do a ton of research. And stalk royalenfields.com; I see plenty of bikes in Cali. There also was a racing green 535 in maryland recently on royalenfields.com....I know its far but worth looking into. Good luck. Who knows just when I was about to give up my bike plopped into my lap.
