New Clutch Suggestions

I've been getting a lot of slip at low end especially in first gear. Im looking at ordering a new clutch what should I get? I've looked at the gripforce Valeo clutch kit and its seems to be the cheapest at about $220. I heard the autozone kit was about $290. The SLP I hear the best thing about and it seems to be about $350. I dont have any real mods to the car yet, but currently have 2.73 gears with a 6-speed because some idiot just slapped on a rear end from an auto when they blew out the good one I assume. I plan on putting in 3,73 gears very soon. What do you think would be the best clutch kit to go with. I figure spending the $50 extra or so for the SLP would be a good choice considering I am doing the work myself. Also i plan on getting the flywheel machined any suggestions on that?

i went with the SLP, decent clutch for a fairly stock car, All it is basically is the stock clutch disc with upgraded Pressure plate/throwoutbearing, make sure you purchase a new pilot bearing also when you do the install (i think i bought one from Napa for like 10$) :)
