Well, I did some ringing around this morning. Could possibly do a little
better than this but can't say if it's worth it until I get a sample of each

Freescale MMA7260Q, NZ$17.78, MOQ 75 (choke splutter)

Analog Devices ADXL202JE, NZ$18.45, MOQ 6

The prototype's UGN3503 is only $2

Not saying an accelerometer couldn't be used, wouldn't be ultimately
better, and probably absorbable into the retail cost, but if the UGN3503
idea can be tweaked for optimum performance it should be adequate
