I like Aurora products, they're not that expensive and they're really nice. Even Chinese rod ends should last a little while, they don't have the precision or the hardness to last a long time, but they'll work short term.

Oh, make sure that there is proper spacing on either side of the spherical, or the range of angular motion can become really limited. Spacers on either side are a good idea if they aren't already extended-type rod ends. There really isn't any other way to properly fasten the rod ends while keeping everything tight in single shear. And an oversized safety washer isn't a bad idea either if you're in single shear.

If they're squeaking, there are two solutions. Either grease them, or get Teflon lined/coated rod ends. Dry uncoated rod ends tend to squeak just like everything else that makes polished metal to metal contact.
