Foci I think might have even worse resale than Contours, so you may find some good deals there. I wouldn't be looking at any Foci from before 2002 though, as they were so full of problems. Anything built post 02 though has since landed the car back in "reliable transportation" territory.
You'd probably find that with some decent tires, a ZX3 is actually a very fun car to drive despite being low on power.
