What is the cheapest Historical Methods/Historiography course?

[Pelican]

I am working on my TESU BA in History degree plan. The most difficult part is finding a course fitting the Historical Methods/Historiography requirement. Searching the forums, I've found these sources:

• FHSU, HIST 379 - Historical Methods, approx. $669 (only available in the Fall semester).
  
• APU, HIST300 - Research Methods in History, approx. $860.
  

BYU seems to have some independent study classes that fall under Historiography, such as HIST 350: British Family, Local and Social History Research (approx. $564), but since that is a narrow topic, I don't know if that would transfer in to meet the requirement.

I checked every public university in my state, for in-state tuition rates, schools in Nevada, few couple of other schools I know have affordable out-of-state tuition, but I could find no on-line Historical Methods course.

Does anyone know the most affordable source of this credit?
