it somewhat depends on how you want it to use in the future. youre talking 
about just one sensor, while all these solutions provide inputs for serveral 
sensors. since i can speak only for myself, and thus the multio: if you 
intend to use more sensor/button/light/etc... stuff in the future, it would 
be an option for you. it costs more than the arduino (and maybe other, 
smaller units as well), but is cheaper than most other, bigger units.
its no problem that you can get a unit that is ready-to-use, no need that you 
have to solder it yourself. if youre interrested, contact me off-list.

as for the bend-sensors:

but since you are going to meassure air-flow/pressure, you could also use 
pressure-sensor:

you probably want one with 10 kpa maximum to get a usable readout. not that 
they are available as free samples ;-) id suggest you to grab one with a 
unibody case, like the mpx5010dp (dp = dual port, one side is sensitive to 
positive pressure (blow), the other to negative-pressure (suck))
