Hey Raleigh Comp, you sound really smitten by this bike.
It happens and there is nothing wrong with that. Off-brand bikes are cool anyway, but honestly, it's Italian, it has an SL frame that fit's you perfectly, with a decent Campy drive-train, so what's not to like? If it is something you really like, then the price might be worth it to you. In the end, who cares if you pay $100 or so extra if it's a bike you really want? Your the one that is going to ride her, not anyone else. I love SL frames, and you can trust Gomango's opinion for sure on her ride.
So if you buy her, no regrets, just enjoy the ride!
