I got mine four years ago in Texas, it should cost about $4000 if everything falls in place, ie the weather stays good the whole time, planes don't break, there are no delays getting your FAA medical etc, all of these things mean that you may not fly atleast once or twice a week. For some people that means that it will take a few more lessons to really get proficient.
I guess there the short answer is that if everything works out perfectly and you get done right at the FAA min of 40 hours then $4000 is a good general estimate depending on the exact prices, but expect to spend alittle more than the minimum.
