Programmer salary in Israel?

I am a Ruby programmer with 2yrs of Ruby experience, and about 4yrs of PHP. I've recently relocated to Israel from Ukraine. And I'm current in doubt whether should I agree to any job offer I got so far. There's this survey of about 600 Israeli developers (year 2012) and seems like the average for a web developer is about 4100$ gross (ranging from 1800$ to 6800$). But all the job offers, after a few days of negotiations are limited to about 3200$. Sometimes it's even less, but they're offering more bonuses like better health insurance, and company car for a small monthly fee. Am I wrong to ask for an average salary with my years of experience? Is it really 4100$ an average here?
