cheap accelerometers, gyros, IR sensors... where?

Hi,

I think it would be good if we would have a list of companies that produce cheap accelerometers, gyros, IR sensors.

Most of us use them in UAV projects and having this kind of database would be of great help.

I will start the list with a question: Where can we find cheap accelerometers, gyros, IR sensors? Can anyone give some input?

E.g: good accelerometers, gyros- analog devices www.analog.com

IR sensors- Planartechnik GMB http://cms.hlplanar.de/index.php?spath=338&lan=1

Thank you and I wait your inputs too. I am also looking for cheaper sensors… day by day

You can get free samples of their accelerometers from Freescale.
