Nismo coilovers?

I was looking at the Nissan Parts Store on the link up at the top of the screen and was looking at their selection of Nismo parts. Anyone ever used or seen someone that used the R-Tune Coilovers? Are they good for budget stuff, seem pretty good price at ~680 bucks. I am going to have to buy the Nismo LSD for sure, thats an awesome price at $750. Here is the link if it doesnt show: http://www.nissan-auto-parts-dealer.com/
