For that price range you can get a set of General UHP Exclaim, they are rated M+S but are really pure summer tires. One complaint people have about them is soft sidewalls, just something to keep in mind.
These are the same tires skperformance drove over a truck driveshaft on the highway with... and he said the sidewalls were still in good shape... even tho his rims were bent like a crushed tin can.
Many people I spoke to like these Toyo's... whether they be the T1-R or the older T1-S.
As for me... this spring I will be bolting on the Goodyear's... and will be looking forward to taking off-ramps at 200 km/h... lol (just for legal purposes... this is a joke... I'm not actually taking ramps at 200 km/h)
It's so funny... I remember one time me and this Audi were driving on Hwy 401 east to Hwy 427 north. You know that crazy long ramp... well we both went into the ramp hot... but all of a sudden the Audi driver braked heavily... not me tho... I just kept going on the long ramp and saw the Audi's headlights getting farther and farther away. lol
I bought GoodYear F1's from one of the members here. i bought them with the rims for $635 shipped. Looks like a good deal since they have 90% of the tread. Since I need just the tires I will have those rims for sale soon. So if anybody needs them let me know. Thanks
