Listening to iPod in car

I have downloaded about 6 days worth of iPod podcasts. I need a way to listen to these in the car. I have been searching for a good device that will allow me to play the iPod through my car stereo speakers. One of the products I have been considering is the Monster iCarPlay Plus Wireless FM Transmitter/Charger for iPod. I read these reviews and I can’t seem to find a good consensus. It think that that is one of the problems with reviews, everyone has an opinion and personal preference clouds the review. I do it all the time. I dismiss something that I don’t find appealing maybe not on specific merits but rather on personal preference. I’m not sure if these reviews are making the purchases easier or harder to make.
