Basic3D concept drawing video buying advice needed

[wtdedula]

Hi All;
I'm looking for a good tutorial on this site to help a beginner develop 3-D concept illustrations of 3D objects such as vehicles, spacecraft, robots, etc ...

I already have the videos "Basic perspective form drawing", and "Volume 4 - How to draw Hovercraft and Spacecraft" both by Scott Robertson and would like to see someone else's style if they are particularly suited for the beginner (who can't draw - yet). There seems to be a ton of videos on here about the subject of perspective drawing so not sure which to chose. Any thoughts anyone ?

The Harold Belker and Alex Jaeger dvds would probably best suit your needs.
