Help choosing a good lift setup

I am sure that this question has been asked numerous times but I want some advice from people that have done this before. I have an '05 and I have been researching several options for a small lift I want to put on my Xterra. I want to level it out and lift it a couple of inches, so about 3" in the front and 2.5" in the back. From anybody that has tried this is that the appropriate amount of lift in front and rear to level it out and what suggestions do you have about kits/manufacturers?

THESE guys are the best for a Gen 2 Xterra:

BTW - "Level" is not a great thing....they all come with a nose down attitude to save gas, and, the steering geometry works best at that rake, etc.
