Sketchup is FAST and I love their toolbar. I have nightmares of using AutoCAD (not really) and Sketchup is like butter.
If only Maya3D was like that. I never even used the program before, I watched the demo at Macworld, then hopped right on and made a nifty 3 story building with a molded roof.
Fun fun!
Oh yeah, their freebie was a pair of socks that says: "Sketchup. Software that doesn't stink."
