Longest Job Interview Process

I'm very happily employed, however lately I have been looking for something a little closer to home (my office is 2 hours away) for some long term stability. I was contacted by one of the largest home builders in the county for a Land Development PM position - local (I can carpool with my wife). Not being one to shy from a potential opportunity, I said I was interested. So far the interview process has been seemingly necessarily long and time consuming. This is how it has been so far:

1) Company (actually 3rd party staffing company) calls me, does a 20 minute phone screening/pre interview with some canned questions. I.E. - why are you interested in our company? Describe your best manager? What are you looking for in an employer?

2) Staffing company says they would like to set me up for a pre-employment test at the company's main office. Ugh, one of these "personality" tests I always seem to fail. OK, no big deal, the office isn't far from my current project.

3) Take test at office, takes an hour, await results.

4) Staffing company calls 3 days later, would like to do a telephone interview. Didn't we already do this? (see step 1). Proceeds to ask same questions in step 1. Staffing company wants to set up in person interview. Ok, I've come this far I might as well meet someone there.

5) Interview with VP of Development. Great interview, lasts over an hour. Talk everything from cost projections to wakeboarding. VP says they are interviewing 9 (really, NINE?!) other candidates and they will call when they narrow down 1 or 2. Alright, I don't really care much. Like I said, I am happily employed. I threw out a high salary number (20% raise) so if it sticks it is worth my time.

6) 2 weeks pass, staffing company calls again. Oh right, I actually almost forgot about this job. They want to bring me in for ANOTHER interview - this time with the division president of said home builder.

7) BUT WAIT, THERE'S MORE! Before the interview they need a quick screening and quantity take off, so I need to come in one hour early.

Has anyone been through such a rigorous (time wasting) interview process? I'd be half tempted to drop the whole thing all together if it weren't for the fact that a) I dont want to turn down a meeting with a fortune 500 company executive and b) I asked for a ridiculous amount of money which they don't seem to question.
