"And interface is just preference...kinda like underwear :)" So, Lightwave is like a good set of Briefs? Form fitting - Good tight control over every aspect. Carrara 4 Pro more like a nice loose pair of Boxers? All the vital parts covered, less control than briefs (once in a while something unexpectedly falls out during use). That price is very tempting, but I think I need to spend the next few years learning and using the apps I already own. mdc
