I'm in Los Angeles at the moment, I'd be happy to give you a tour. Also, Carbide 3D is over in Torrance (other side of los angeles from me) but still doable on a hard-day's drive from Vegas.
There really isn't too much about the machine that's scary, well, other than the whirling metal bits.
The big suggestion I have, if you're trying to get it all figured out, is to start with a decent CAD program. Depending on what you're looking to make LibreCAD is great if you're doing mechanical components, and is free, some of the cloud based systems that people throw around on here are ok.
I guess the big question is, what are you looking to do? I do mostly mechanical design (I build machinery) so I'm using Solidworks to generate the material I'm looking to cut on the SO3. This is probably a vastly different world than people who are using the SO3 for more artistic work.
If you want to come down, just need to give me some notice. Before you do, I'd like to get a better feel for what you're looking to do and give you some reading material so you know what I'm talking about and can make the most of your trip.
