I agree, Eovia has done a remarkable job on making booleans better. I made the rounds at Siggraph last year to all the software vendors booths and found out that booleans are a pretty dicey operation for Maya, Lightwave, Cinema 4D and all the other 3D programs out there, regardless of price. the only one that had no problems was Form-Z and that's because it's a solids modeler and all the rest are surface modelers. Carrara also falls into the surface modeler catagory.
