You must not have visited some of the same websites that I have.

This is pretty close in price to that denon crap, but worth the money:

Even if the material is unclassified, which is very likely considering the coverage so far, there is another set of laws that cover anything related to military specifications: ITAR

The penalties for ITAR related violations can be almost as bad as those for sharing classified materials (which is treason).

Typical human has about 10k ohms resistance (varies depending on moisture / sex / part of body, etc). It takes about 10mA through the heart to kill. So 110 AC RMS voltage is easily lethal, and no problem at all for even the cheapest generator to maintain that power load (~1 Watt).

Feel free to experiment and/or google if you think I'm wrong.

If you are worrying about that, you are doing things very wrong. The utility is presumably supplying no voltage; hence the need for the generator, and if it was, the last thing you want to do is to use your generator on the same circuit as the utility power.

Not sure which would be worse, being completely in phase (which would double the voltage), or completely out of phase, which would (try to) create about a 320 peak to peak voltage between the utility supply and the generator (or vice-versa), and cause some great fireworks. Remember that single phase AC power (what you have at your house) is just a basic sinusoid (ideally, anyways), with some theta that indicates its 'phase'. All the math you can do with sinusoids is true for representing AC sources; you just need to remember that you don't have loss-less paths, infinite current sources, and 100% efficient supplies.
