My experience when doing some recent FM antenna testing is that the wire dipole that comes with most FM tuners beats the pants off of most other reasonably priced antennas when mounted indoors. This includes the Magnum whip and about a half dozen other antennas. It may not be as easy to hide, pretty to look at or as easy to re-orient for different stations as a vertical whip or "artistic" looking gadget, but it did pull in more stations with better quieting and increased signal strength. It was also less sensitive to the surrounding environment i.e. it was not as easily detuned by walking around or placing it near metalic objects.
The suggestion of using the Magnum Dynalabs Signal Sleuth is quite valid. I have a few friends that use them and all are very pleased with the results. These can be used to amplify the desired signal, reject out of band interference, reduce noise, etc... In the RF field, this is known as a "pre-selector" and can make a very noticeable difference, especially if you're experiencing marginal reception. It will not give you what a giant outdoor Yagi mounted on a tower with a rotor would do, but some folks aren't that lucky to be able to do that ( or even want to ). As such, those with more restrictive antenna installations or those way out in the boondocks, you might want to consider trying one of these. Those that are station hoppers might find it somewhat tedious trying to fully dial in all of the controls station by station though.
I also did a post on how to make a vertical center fed dipole using two pieces of wire and some coax. You might want to do a search using FM antennas as the subject. Might work okay for you and cost next to nothing. Follow the directions as closely as possible though for best results. Sean
