I've also heard rumors that GWiz is no longer in production... Can anyone more informed than I confirm or deny them? I'm definitely eyeing MARSA as a replacement, Gus just loves them!What consensus? the LCX wasn't even mentioned until your post.

ADXL375 3-axis 16-bit 200 G digital accelerometer, $5.74 in quantity over 100 available ub September.
You don't need an accelerometer for a dual deployment altimeter. Current baro units work fine to 100 kft and use Kalman filters to eliminate Mach delay timers, and cost less than $100. Stick a $5 accelerometer into a $100 altimeter and you get a Raven, or similar altimeter for ~$150.

Larry, no reason to get depressed.
Here is a plot of data from the MARSA54 on Gerald Meux min diameter N5800 flight at LDRS. He posted this data in his video file and was kind enough to share the data with me.
Blue is inertial altitude, red is barometric. Flight to 30K pretty decent integration wouldn't you say? He also used this data to characterize the motor and it estimated the thrust curve and total impulse of the N5800 within 10% of the certification values.

I don't know if they're still in production, or not. I have heard from several folks who've had problems getting in touch with them over the years.
