Go for it. Have one now, bought for a cross-country trip about 6 months ago. Word of caution though, just last week the plastic stems (all four) to hold the phone/GPS horizontally started to break at the screw points. What may have happened is the screws were too tight for too long, but it was just interesting that all four broke within a week. TwistedThrottle is sending a replacement unit, so I ain't even worried. It was 100% solid for those 6 months though.
I've had a Arkon Bicycle Cell phone mount on my FZ8 for 7 months. I drive daily in the city with horrible streets and on the weekends I take 200 too 400 mile runs on highways and back roads. Works great!!! I even put a handle bar mounted USB/Cigg lighter power supply on my bike. Both work great!!
