If you really like the group of programmers, and you really want to move to the Bay, that's worth something, take that into consideration. And, there's always the "chase your dream" scenario that's worth something as well.
As to the stock options: If those are the ratio's, you're not going to be getting much if the company gets acquired. Think about it this way. If there are 3000 shares outstanding, and you get 4 shares, you own %0.13 of the company ( 4/3000). Now, whatever the company gets acquired for, you receive % 0.13 of that amount. So, if the company gets acquired for $10 million, you get $13,000. $100 million, and you get $130,000.
As an aside, there are precious few companies getting acquired for $100 million. There aren't that many acquiring companies that can afford it.
Another issue: There is a lot of competition in the Bay area as opposed to other parts of the country. There are a lot of incredibly smart people out here with several degrees and tons of experience. San Fran has some of the highest per capita Phd's in the nation. It can be a bit intimidating when your first arrive. You go from being one of the elite geeks in your small pond, to being just another techie in a huge ocean of nerds.
I've known a couple of people who came out here, and felt blown away by their own lack of education. It's easy to feel pretty inadequate. Paul Graham can write about the problems with the educational system, but Paul also has his PhD in Computer Science from Harvard. So, take that into consideration, too. He also recommends people finish their college degrees before starting their startups.
I've always been one to chase my dreams, however despite what anyone else said. If you really want it, you'll find a way to make it work.
