I haven't use the quest altimeter. It sounds like a good value for what you get.
I do have a Perfectflite Alt15K. It will fit into a BT-20 tube, measure altitudes to 15,000 ft and store the flight profiles. It beeps out the altitude instead of an LED so you can hear the altitude instead of having to disassemble the rocket to see the LED flash. You can then download the data and see and calculate various flight profiles. It will store 2 or 3 fights in memory.
The best price I've seen for the Alt15K is $71.20. It's another $20 for the USB interface cables to download the data.
