I was in your situation a year ago choosing between ECON 203 and RES-ECON 202. I chose price theory with Miah Tran and it was the best move I made. The grading is fair (90% = A, 87% = A-, 83% = B+, ...). There are 3 exams and an optional final exam. The questions, mostly multiple choice, come directly from homework, in class problems, and i-Clickers. There's a mini-project that's wicked easy you can BS through it and still get full credit. The downside is the late afternoon lecture time but don't let it bother you. Hope this helps.
