I took 0.02 USD/hour for on-demand micro instance; 0.007 USD/hour also requires a $52/yr or $82/3yr fixed cost on top.
I have no idea how to predict the spot price, and I haven't tried to collect statistics on it, so I (personally) wouldn't choose it for this kind of application, where you expect it to be there all the time, not just when it happens to be cheap.
I mean, 3 USD/month, or 30 USD/year, is cheap enough to pay once and forget about, rather than worrying about turning it on or off.

It's not very difficult to set up a script to spin up an on-demand instance if your spot instance gets nuked. Or to just buy another spot instance at a higher price.
Thanks for the clarification -- that makes sense. Given amazon's 1-year-free offer and its excellent documentation, I'd still use an EC2 instance for this purpose.
