Bill, the Griffin was the ONLY one that worked for me. I started with a $10 adapter which made a tiny bit of whirring noise from the tape drive, but was otherwise ok - then that went to the little lady's A3. Then I "splurged" on a $20 Sony adapter. I made it the far end of the Best Buy parking lot before turning around to return it! It made an unbelievably loud racket from the tape drive mechanism and it had a builf-in hissing sound, too. What CRAP!!

I went back this past Monday and got the Griffin, and am VERY happy with it. My wife's big complaint with the regular adapter (we're still waiting for Audi to come out with their iPod adapter) is that whenever she gets somewhere, she has to remember to turn off the iPod when she shuts off the car, otherwise the iPod will keep playing and playing until its battery dies. The Griffin eliminates this problem nicely.
