07 585 on sale for $2,495. I am also considering a 595 ($3,695) but the price for the 585 is significantly less. What are your thoughts on the performance trade offs versus the reduced price for the 585? I have no plans on racing, however, I do ride 20 - 30 miles 5 days a week and often train with friends that are active racers.

Based upon your use, the 585 should be more than enough bike, unless you have no budget. Take the savings and invest in a set of carbon rims.

You may still be able to find an 06' for a little cheaper as well check out B&L Bike and Sport's Ebay store. They are a reputable bike dealer in San Diego, CA that had a few 06' frames to get rid of. I picked up my 06' frame for $2,300 off of E-Bay back in August 06' and could not be happier.
