Just chiming in to say that my LBS also did my bike build for $100 three years ago. I took them the frame and fork I'd bought on ebay, but I bought everything else through them including Campy Chorus gruppo (except saddle and pedals), so I am sure they made a lot more on me than the $100 with the markup on the parts (even though they gave me a 10% "good customer" discount)!
