I'm working on a problem in multiplicative ergodic theory, and Mahler measure has just made <a href="http://www.birs.ca/workshops/2003/03w5035/report03w5035.pdf">*another*</a> appearance. I am looking for a uniform lower bound on Mahler measure over all polynomials of *fixed degree* with complex coefficients (not necessarily monic) where the largest coefficient is of absolute value 1. 

I found an ugly bound that is exponential in the degree, but am hoping for something in the literature or something a bit prettier. 

<blockquote>
Can anyone give me a reference (or simple argument) for a lower bound for Mahler measure of degree $d$ polynomials (not necessarily monic) in a single variable (with complex coefficients) where the largest coefficient is of absolute value 1?
