You can get them for $10-$20. Once made, they don't need to be pressed again. Reheating them depends on what you want to do with them. Microwave, fry, griddle, oven, etc. In this house, we tend to put them in the microwave because the microwave is easy and we make a lot of Tex-Mex enchiladas (microwaved, dunked in enchilada sauce and then filled and rolled). We've also made corn muffins from corn tortillas to use them up or when out of corn meal.
