Revolution Gear is the best aftermarket gear brand. I'd get out of the Quadratec catalog, they're overpriced and their rep's technical chops are severely lacking.what brand do you guys like ?
And since I'm guessing you will have a shop install them I would have them provide all the parts. That way if anything goes wrong they will be responsible for it no matter what the problem is. If you provided the parts they would very likely blame them when it's actually usually the installer that caused the problem.
