This is my own experience from what I saw on Craigslist recently (give or take a few bucks here and there)
1. Frame/fork - $600 (let's just say that's how much you get it for)
2. Wheels - something like Fulcrum Racing 7s - $160
3. 105 groupset - $500 (let's just use this number for now)
4. Cockpit - Uhh...let's say $300 (stem, handlebar, seatpost, saddle?) Maybe less or more. (I have a spare handlebar, stem and seat post!)

5. Misc - cable housing, bar tape, and what have you etc. $50
That in itself is already around $1500 and change. Nothing wrong with a 2011 model. The Specialized would come with a warranty and the geometry is VERY similar to the Scott CR1.
I'm biased having owned a Scott myself and quite enjoy the hunt of building a bike. On the other hand, I prefer SRAM over Shimano. Then again, not everybody is as ADHD as I am.
