I searched the web for oxygen sensors and found many sites. Search for
+oxygen +measure +sensor +circuit
Here's some interesting sites, one with your 10 LED's:
http://www.students.tut.fi/~eppu/dev/EGO-bar.html
http://www.forparts.com/BoswidebandO2.htm
http://www.customsensorsolutions.com/zn-air.htm
http://www.flash.net/~lorint/lorin/fuel/lambda.htm
The local auto parts house can probably sell you a cheap sensor, but you may
want to find the circuit you want to build first. Bosch has a good article
on the newer wideband sensors.
Good luck, let me know what you finally build,
Gery
