Unique Blog Designs - Or Broken Blog Designs?

Today I was listening to the first of two podcasts in which John Chow hosted the Shoemoney Show. One of his guests was Nate Whitehill from Unique Blog Designs. Nate is known for redesigning both Chow and Shoemoney's blogs. Although his work is unquestionably great, I was a bit shocked to discover that many of his designs render horribly in IE6 (see pics below). Based on stats from my own sites, the majority of my visitors are still using IE6. Given the $750 price tag Nate charges for a new skin, I would expect the design to be cross-browser compatible.
