I have the iTrip and it is a piece of junk. The battery won’t hold a charge, and it is out of warranty now. In every respect, it is poor quality. I have not plunked the money down for the $70 FM transmitter from C. Crane yet. I am of the opinion, based on what I know of the company, it is a quality product.
the iriver AFT is too expensive for me. do you know anything about the Soundfly SD WMA/MP3 Player Car Fm Transmitter for SD Card, USB Stick, Mp3 Players (iPod, Zune)
