A generic platinum RTD with get you a 100th of the way there for about $100.

There are also precision thermistors that are about as accurate for about the same price.

A metrology grade platinum RTD will get you a 10th of the way there for about $600.

I assume you already have signal conditioning hardware that's every bit as accurate?

Your pockets must be deeper than mine. I'd stop at $50 and 0.25
