FM Transmitter

Would like to take my Blackberry loaded with music on the road and was wondering if you could recommend me a good but cheap FM Transmitter that's not gonna hurt my wallet but give me good service overall.
I've seen a cheap one at WalMart but not sure of its performance.

Blackberry has a 2.5mm jack but that's easy to fix with a 3.5mm jack adapter.

Thanks

Most Fm transmitters work fine. Ive tried all different ones from $20.00 to $100.00 the more expensive have more channels. The biggest problem is if you live in a real populated area with tons of radio stations. You may need to spend a little more money. Try the one from Walmart you can always return it.

If you are worried about the modulator picking up what it shouldnt, get the type that installs directly between the antenna and the radio.
