We present an improved technique for the deprojection and PSF-deconvolution of X-ray surface brightness profiles of galaxy clusters. Our method is tested using simulated profiles, XMM-Newton and Chandra data, and is shown to result in unbiased gas density profiles that retain full information about the gas distribution. We then apply the method to surface brightness profiles of an unbiased sample of nearby clusters from the XMM Legacy Project for the Study of Galaxy Cluster Structure, and
