Not sure what wheels you have, but if you have 18" rims you can find some good deals on slightly used Goodyear Asymmetric 2's - they're OEM on Focus ST's. The ST crowd often either wants all seasons, or they go the other way and want max performance tires for track/street duty. You'll see them on craigslist from time to time, 235/40-18's, like here:

I know you don't live in the NE but that's just an example - $350 is common, and probably negotiable for a good set of 4 tires (I got my nearly new set of four for just under $200). Very responsive sidewalls, better in the rain than MPSS, and just slightly worse than them for dry traction. They're still not all seasons though, so in the winter they'll lose a lot of grip just like any other high perf rubber will. If you have 18" rims and can find a set locally, they're huge bang for the buck IMHO. Good luck!
