They have some pretty tall ratios in tasers, but they might not be one stage. Though i have heard claims that they can be made. Kettering ignition is pretty tall too (> 1000:1).

I have found out that the normal single use camera is actually a recycled / recyclable camera. It is more nearly one use per user.
Correct, but a Kettering ignition is NOT low power; a car battery cannot be well compared to a single AAA cell. :-)
You could probably adapt a CCFL inverter, or at least take the transformer out of one.
You could also start with an EL inverter out of a clock, but you'd have to add a voltage multiplier to the output.
The transformer in those is rather lossy; the square wave input drive results in a sine wave even for a resistive load, and the power that can be obtined at the output is rather low even if you drive the input with a number of watts - even at "resonant" frequency.
