Here, let me DigiKey parametric search that for you
The LMT87
http://www.ti.com/lit/ds/symlink/lmt87.pdf is the cheapest one I could find on DigiKey that is actually rated up to 150C, excluding NTC thermistors or just using a diode or transistor.
With a typical thermistor you'll need to do the maths to convert its resistance function, which is exponential and not linear, into temperature. Having a semiconductor device with a linear output is tempting.
I often like using the Microchip MCP9701 (or others in the MCP970xx family) for non-critical temperature sensing applications accurate to within a couple of degrees, for environments below 125C. They are very cheap, and linear, and without any external components or annoying maths. But only rated up to 125C.
If your 150C Tmax specification can be compromised a little bit, say to 125C, this is likely to significantly open up a wider range of candidate options and cheaper choices.
