Kinda odd, I was in the same situation a few weeks ago. I saw a FZ1 at a dealer and we started talking. I rode it was thoroughly impressed, the power, handling, and brakes felt great. They even game me a great deal, it was an 07 with 5K and they wanted my bike (as close to stock as possible) + $4K.
In the end, I couldn't do it either. I love my bike, and it has become part of my life. I think I'll keep it 'till it dies, then look for another one.
