I have been seeing these endlinks for my 2005 g35 on a few websites including conceptz and enjukuracing They seem to be pretty good although I can't find any reviews. Anyone used them? or should I just go for the next step up which is the whitelines.

Price is attractive, but cheap helm joints can be clunky and will drive you nuts. They are not protected from road crap and can wear much faster from exposure to weather.
I never had issues with OEM, even on the track. If you really need something bulletproof, go with Whiteline, they will not clunk and have rubber boots to protect the joints.
