About to need some new tires... help

[speedoflife]

Hey guys. Since the majority of you all are far more knowledgeable and experienced in the area of tires, I figured this would be the best place for me to pose my question:
I need to get some new tires for my car. The size is 225/60/16. The OEM tires are Eagle LS's. (Sucky)
I'm sort of narrowed it down to the General Altimax HP's and the Eagle GT's. I've heard that General has made generally mediocre tires in the past, but I haven't enough experience in the matter to give a reasonable justification.
Any suggestions? I'm trying to keep the price down to about 100 bucks or less per tire.
The OEM tires have disappointed me in about every singe area, except they are quiet (my 143.2 dB @ 33 Htz stereo drowns out any noise at all, so I could care less about that).
I am looking for improved performance and GRIP (I have almost no grip at all right now). The car is a Pontiac Grand Prix, and I will need to replace the tires within a few months.
I appreciate any and all suggestions/comments! Thanks guys.
