iRiver AFT-100 (FM transmitter)

Pros: Clear sound, any frequency, three presets

Cons: Hiss in some placements, auto-off kills single-side stereo

Summary: I really enjoy using mine with my Palm TX, however, I often have to handle or raise the wire to eliminate hiss or interference. Additionally, there are stereo talk podcasts in which each talker has been mixed into one channel, and the auto-off feature incorrectly shuts these down after there is sound in only one channel for several seconds.
