In addition, I believe that in both Pennsylvania and New Jersey  
agreeing to
submit to a breathalyzer or blood test is a condition of having a  
driver's
license.  Refusing to take the test can result in an immediate  
suspension of
your driver's license (6 months to a year I believe).

A friend of mine that is attorney recommended not refusing the tests
(especially for a first offense) because he said that at trial a good
attorney would have leeway to present mitigating issues, challenge the
accuracy of the tests, plea to a lesser charge for a lighter  
sentence, etc.
However the refusal of the test was cut and dry and essentially  
resulted in
a mandatory punishment.

While IANAL and I'm not advocating people drink and drive (or avoid
punishment if they do), I thought this was an interesting legal  
perspective
worth mentioning.

A friend got pulled over in front of me for some minor infraction
(into a bike lane too early for a right turn, if I remember
correctly).  I knew he had come from a bar and had probably had at
least one drink.  They started in on the normal dui tests (speech,
eye, coordination, etc) in front of me.  I had enough time before
this to tell him not to submit to a breathalyzer as they're
inaccurate - he said that he was probably above the limit, so I told
him that he could expect that they'd figure this out and he'd be
taken to the police station for a blood test if he refused a
breathalyzer.

By refusing to submit to the breathalyzer, under CA law (or at least
in San Luis Obispo), the officers have the option to place the person
under arrest and take them in for more thorough evaluation.  They did
this - unfortunately for my friend, he didn't take well to being
handcuffed and started to argue/resist.  Probably would have been
treated better had he not.  Ultimately his blood was tested and was
found above the legal limit.  He made a bad choice and is still
paying the consequences but no one was hurt.

However, it should be clear that if you refuse to take a breathalyzer
test, you MAY be arrested.  Whether or not you've ever had a drop of
alcohol in your life.  Refusing the test is within your rights, but
an officers suspicion will quickly place you in shackles and you'll
be subjected to the more reliable (and repeatable) tests.
