Older Bianchi Pricing?
 

Hello,
Newbie to road bikes, my first was a second hand raleigh mixte marathon. I am looking to get a new bike and being 5'1 (5'2 on a good day) I am looking at Bianchi Eros Donna 44cm. My inseam is 29-30cm so the 49cm Eros Donna standover height of 29.5 in is a bit high.

I found a local 2004 Eros Donna going for $900, its was lightly used. I was just wondering if this a good deal as I found some dealers selling a new one for about $930 (as long as it is in stock..)
What would be a reasonable price for the Bianchi?
Thanks for all your help!! :p
