Article on UDP.
I have been browsing at G35Driver.com and have come upon this article. I feel many will say it is a not worth their time and some may say thank you. I do hope the moderators will keep this long enough for others to read and make an informed decision on purchasing these hazards for their Maxima and other cars.
Happy reading. This is the link http://dinancars.com/html/danger_of_power_pulleys.htm

Did you read this? What does it have to do with a Maxima? You don't remove the harmonic balancer to put an UDP on the Maxima. I have had mine for quite some time now, and there are no ill effects unless you are trying to get off the line and hang with me. I will keep this article in mind when I hit the lottery and buy a BMW.

**** retesnive if you do not like what you read then move on, respond to some "What is the best crap can I put on my Maxima post!" I am sorry if you do not like the article,or you thought that I did not notice who it was written by?
No you do not have a BMW , but yes you do have a mind of a neonatal .
Have a nice day .

Shouldn't affect us
This info was a big concern 1-2 years ago in the autcrossing community. I believe Yahoo Groups had about 100+ replies to the topic.Even the terminology and engineering of pulley vs balancer was at question. Mostly Imprezza's and WRX's concerned.
Like Tapout stated, it only affects cars with integrated harmonic balancers. Many cars like ours have separate components and shouldn't fear.

The VQ30 is internaly balanced. The stock steel pulley has no dampening effects. I installed mine along with my new engine, as can be seen on my website. THe car revs absolutely flawlessly. No vibration, and very very smooth. No these are not big HP gainers, maybe 3-5HP on a stock motor tops, but as your mods grow this mod will yeild you more benifit. i.e exhaust may give you 3hp an a stock engine but 5 when you put it behind a Y pipe.When the NA guys get to the end of the road on mods, then $150 or so dollars is not bad for 5HP.

This was discussed not too long ago. The oem crank pulley on a Maxima does indeed have a thin rubber ring that acts as a harmonic damper to damp out torsional vibration. However, the general consensus is that it is not critical to have one based on the experience of many here in the org who have aftermarket UDPs without harmonic dampers and have experienced no problems. The reason the BMW inline 6 has problems with UDPs is due to its longer crankshaft, which lowers natural frequencies of vibration and increases the amplitude of vibration at the natural frequency, resulting in eventual fatigue failure of the crankshaft.

I don't know about best, everyone will have their own opinions. Thats for sure. I have a MotoStorm pulley, and I love. Thats all I can say. It topped the scale at about a pound even. As far as I know, its the lightest one out there right now.
