I’ve always liked the iRiver AFT 100 (although I don’t use an FM transmitter), and it’s gotten good reviews. I also like its looks (yep, those persuade me!).
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)
It looks like the iRiver transmitter often (multiple times a day) is available at eBay at that price, including shipping (thankfully). One also sold just earlier today at $25.50 (with free ship). You should be able to find something in your price neighborhood.
I just wish it still was available at the earlier, lower price for you! I just can’t find it around at that pricepoint anymore.
