I'm looking for a "linear thermocouple" or a thermocouple that is relatively linear over a range of 70-220 degrees Farenheit. By relatively linear, I mean that I could allow an error under 2 degrees farenheit in that range. Anybody know anything about this, or where to find good charts? I'm trying to make this inexpensive.

Ohm-Jack is correct. Type J or K thermocouples are about as linear as you can get in that temperature range.
R^2 for a linear regression is 0.999956 for type K (that's more than enough for your requirement).
Tables are here (scroll down for the list of types):

Try an LM50 . (google it).
It's an I/C with very low mass and works up to 125C.
