Amo Houghton, the previous holder of the 29th's seat in Congress, is considered an independent, centrist Republican. He voted against the war in Iraq and was one of the founders of the centrist Republican Main Street Partership. Let's compare his voting record with self-proclaimed "Independent" Randy Kuhl.
Using data from the last three sessions of Congress, I ranked Kuhl and Houghton against their peers in the Republican party on a simple independence metric: the number of times that each voted against the majority of their party.
In the 108th and 107th Congress, Amo Houghton voted against his party 16% and 20% of the time, respectively. So far in the 109th, Randy Kuhl has voted against party 9%.
This graph plots the relative independence of the 29th seat in the last three Congressional sessions, and compares it to some other New York Republicans. The top line is retiring Rep Sherwood Boehlert, NY-24, a moderate Republican. The bottom line is Rep Tom Reynolds, NY-26, who's considered a party loyalist. The red line represents the "middle of the road", and the blue line is the 29th. As you can see, in Kuhl's freshman term, the 29th went from being quite independent to being one of the more reliable party votes.
Again, Kuhl's slogan -- "Accessible, Independent, Effective" -- is suspect when you go by the numbers.

Notes on the data: For the 109th, this report used the dataset
of votes created by professors Jeff Lewis and Keith Poole, and
limits votes to those taken prior to September, 2006. The 108th and 107th use Poole's voteview datasets. Any errors here
are mine, not theirs.
