John over at Hexus has taken a look at five popular FM transmitters available for your portable music player of choice. I personally prefer using a tape adapter in my VW's Monsoon system.

"It was only late last year that FM transmitters finally became legal to use in the UK. Now that manufacturers have had the chance to sort out their products so that they conform to the new regs, we thought it time to look at a bunch of transmitters to compare their merits."
