The frameset option has a Headset and BB already? Those are two of the most Pain in the ass parts on old french bikes so thats a good thing.

I bought a complete bike and ended up just using the frame, fork, heaset and BB. Here's what the rest cost roughly.

Handle Bars - 45
Bar Wrap - 25
Stem - 30
Brake Calipers - 30
Kool Stop Pads - 25
Brake Levers - 45
Brake and Shifter Lines - 25
Front/Rear Derailleurs and Shift Levers - 50
Crankset - 45
Pedals - 30
Rims - 50
Spokes 50
Hubs - 40
Tires & tubes - 60

like 500 bux probably. I try not to do all the math
