Hey, be cheap, don't waste effort on negotiation if you are ok with less money! I think that's totally reasonable. Just don't broadcast it that way. It attracts the wrong kind of attention.
Being cheap is funny. In San Francisco at my last job I was around $175k before the expected bonuses which never materialized, as they tend not to @ start-ups. To no avail I tried hard to sell myself on "$100k and I only work 9 months per year", but there's such a false notion that "bodies in the seat mean productivity". I ended up finding a gig around $110k, which provides me a far better lifestyle in the cheaper part of the Balkans/Near-East than I could afford in any US city where I would want to live.
This is part of the problem: golden handcuffs.
