Mp3 Player FM Transmitter reccomendations?

[irishScott]

I own a Creative Zen, so anything with a 3.5mm jack will work. Used to use a tape adapter but that broke and I could use the universality. Problem is every FM transmitter I've found either has horrible reviews or drawbacks that I know I wouldn't like (ie: Auto-turn off after 15 seconds and such). Anyone have one they're satisfied with? I live in a DC suburb, so I pretty much need a full-spectrum tuner with a powerful signal. Price range is <=$50.

Thanks in advance.
