I was going to purchase the Haltech Flex Fuel Sensor to use with my Haltech PS1000, but through some searching found that they are just rebranding an OEM sensor and marking the price up. I found that Dynosty is also selling this OEM sensor without the Haltech sticker for $199 (compared to $232 from Haltech).
Through a little more searching, I found the sensor is actually made by Continental and is used in some of the newer GM and Holden vehicles.. and can be ordered from any GM dealership for MUCH less than Haltech.

The only obstacle after obtaining the sensor through a GM dealer is getting the connector for it. Haltech charges $38 for the connector and terminals, Dynosty will sell you the same thing, but marked up to $50. I contacted Continental and was able to get their source for the connector. However, the connector is not available in small quantities. I did find another connector that works if you remove two tabs from the sensor side (I found that Haltech does this also).
Here are before and after pictures of removing the tabs:

The new connector (that costs less than $2) fits great.
