I find TeamViewr to be a much more stable option than go to meeting...

I also find Sketch up to be clunky. I however have a .edu e-mail account so I get autodesk inventor for free. Though that is an 8 gig download and takes a decently powerful computer to run. I really need to learn SketchUp seems to be the industry standard It's just kinda hard to go from a refined and powerful product like autodesk to sketchup so it is mainly a mater of my own will power.
