Oops, I won this Pinarello,

http://tinyurl.com/2jxzcl

and I'm a bit worried that I didn't get much of a fight. I was looking for a nice older steel Italian racing frame and found this and after seeing what similar vintage frames were going for (and dropping out of many auctions along the way) wasn't expecting to win based on my final bid.
I can't find much information on the Pinarello Radius on-line. Sorta having buyers remorse now, but I can't imagine going wrong with a Pinarello at this price (though shipping was about 1/2 the cost of the product).

Any information?
