If anyone is interested there is a new flight computer available called Arecorder. It's a great unit with a precision baro sensor and two accelerometers- 3 axis 24G and a single axis 80G accelerometer and a bunch of other features. I made several flights with Arecorder in the last two years and it really is a great product. I'm not associated with a manufacturer in any way but I used it a lot and I really like it, especially the new version 2.2 that was released recently has some exiting new features (like an option to configure it by computer).
Here are the features:
-pressure measuring in range 0 – 110 kPa (in range 50 – 110 kPa with 100 Pa accuracy),
-acceleration measurement – three axis +- 24 g, one axis (along rocket axis) +- 80 g,
-temperature measurement inside rocket in range -50 to +130 °C (-58 to 266 °F),
-data recording into microSD card,
-frequency of data sampling 100 Sa/s,
-Kalman filter implemented to reduce noise in pressure data,
-detection and signalling of connected fuses,
-firing up to three fuses – two parachutes and one for second stage engine ignition,
-firing main parachute when altitude parachute failure is detected,
-detecting and recording inclination of rocket at launchpad,
-measuring of Arecorder’s power supply,
-programmable delay between burnout of first stage engine and firing second stage engine,
-selection of one of four sets of Arecorder configuration parameters,
-Arecorder’s configuration parameters and owners first name, last name and phone number programming by software installed on a PC computer,
-writing summary of several most important flight parameters into separate file.
Arecorder was developed in Poland (Europe) by Arek Palinski with help from members of Polish rocket society. His customer support is top notch as he is very quick to answer emails about anything you might want to know about Arecorder. You can contact him by email: [email protected]
What is the price of Arecorder? I paid 60Euros (about $67) with shipping included. For US customers the shipping is probably a little more.

In 2014 I did a test flight where early version of Arecorder was flown together with Perfectflite SL-100 for comparison. Bellow is the data from this flight. As you can see the data from both altimeters almost perfectly match.
And here is the video from this flight:

Overall I think this is an awesome flight computer for a very good price. Here in Europe it was flown numerous times on all kinds of rockets, subsonic and supersonic and it proved itself as a very reliable, workhorse altimeter.
