3DGeni.us convincing me to try out 123D Design

I wasn't so sure about 123D Design before, but this bath plug tutorial on 3DGeni.us makes it look as easy to use as TinkerCAD, with even better features, and still free (as opposed to $120 a year). When I get some time I'm gonna try making a chess set in it and see if I can start recommending 123D Design. Plus the tutorial is top notch. Check it out.
