Well I'm just going to give you opinions on tires that I have used:
The Hankook RS-3s that were suggested are a great dry tire with maximum grip but I think it is pretty extreme for a daily tire. The tread life isn't that great. I used those primarily for autocross. From the looks of the tread, it looks like water evacuation wouldn't be that great in heavy rain.
I have tried Dunlop Direzzas and those are just ok. Mediocre grip but gives good feedback of when you are at the limit. Some tires don't give any warning when you go over the limit and they slip. One bad thing about them is that they get freakin' loud. I'm probably about 1/4-1/3 of the life into the tires and they just howl. Worst part of the tire.
So far no complains about the Hankook Evo2s. Pretty decent tire. Since you are just looking at summer tires for next summer, keep your eyes peeled for sales. Usually Discount Tire and Tire Rack have Fall/Winter sales on summer tires.
