I’ve finally gathered sufficient data to provide a moderately thorough analysis.
FM transmission isn’t a necessity for me. I have alternative modes of connecting my iPod to my sound systems. I’ve played with my iTrip both in a home audio system and on the road. I’ll compare and contrast the Griffin iTrip and the Belkin FM Transmitter in areas of use that I have deemed important.
Supply of Power
The Belkin Tunecast uses two triple A batteries. This is bad because it adds unnecessary bulk to the device. Too, if your batteries die, it doesn’t matter if there’s life left of your iPod — you aren’t transmitting anything! The iTrip, on the other hand, feeds off of the iPod’s battery power, thus negating any need for an alternative power source. This is great, because the iTrip stays small, sleek, beautiful. Also, you can transmit for as long as your iPod can play.
Winner: iTrip
Appearance
The Tunecast, if you can see, is a decent enough looking device. However, it doesn’t quite match the iPod like the rest of Apple’s suite of products. It has a rather unattractive cable, making it more of an awkward dongle than a sleek iPod accessory. The iTrip fits right on top of the iPod, acting as an extension of the hard drive herself, as an arm is an extension of the torso.
Winner: iTrip
FM Frequencies
The Tunecast has four options: 88.1, 88.3, 88.5, 88.7. The iTrip can transmit at all odd frequencies from 87.9 to 107.9. The iTrip clearly beats all there, however, the switching between frequencies does offer a bit of a dilemma. The Tunecast merely has a physical switch to change the frequency, and a physical button to activate and deactivate the transmission (brownie points for simplicity). The iTrip, having no moving parts, does positively the best it can do under such circumstances: you change the frequency through the iPod’s software.
Before you can use the iTrip, you must first add MP3 files to your iTunes library, each MP3 containing the commands for each distinct frequency. Each MP3 is five seconds and 89k in size. There are 103 command MP3s total, which adds to about 9MB (not that much, considering the outrageous size of the iPod). Then, you sync the iPod, thus adding the MP3s to your iPod’s library. To select a frequency, you must then choose the FM frequency from your iPod’s library, and then pause the MP3 to show the iPod and iTrip that you intended to change the frequency, not that the frequency was chosen through a shuffle.
So, for simplicity, the Tunecast wins. But, for functionality and simplicity given the circumstances, the iTrip wins. Plus, you get boatloads of frequencies with the iTrip. That can’t be beat.
Winner: iTrip

Personal Use
I had a miserable time operating the Tunecast. I was disappointed while driving in my car — the stations it could transmit are all used by local radio where I live. I did not even try operating the device in my home. I returned it two days after I bought it. The iTrip is a joy to use. Using the iTrip Station Finder, I was able to select a station that was clear (90.1 was the first that I tried; it worked wonderfully and I still use it).
I tried it first in my home, and have since ceased using my tape adapter to play my iPod on my stereo. This is a great alternative, because it’s extremely clear and now there’s no longer the noise from the cassette adapter playing.
In my car, there is some minor distortion. However, I’m used to having crystal clear sound from my cable input. Plus, I never listen to the radio, so any distortion at all saddens me. However, if I did not have the cable input, I would be extremely enthused over the performance of the iTrip in this instance.
Winner: iTrip
Summary
The iTrip is sleeker than the Tunecast, provides more frequencies, offered a more pleasant using experience, and (in my personal case) provided a much clearer transmission. The sole downside to the iTrip resides in the slightly more complex user interface (changing of frequency). The Tunecast offers the epitome of simplicity in that regard, and nothing really can beat it. The iTrip is still simple to use, and beats the Tunecast in every other aspect of use, appearance, and operability.
Thus, in my book, the iTrip wallops the Tunecast!
