Complete Le tour - Free
Wheelset - $110
Cog & Lockring - $40
Bars - $25 (But they were a gift)
Saddle - $20 (Used)
Tubes - $7
Tires - $35

So I guess closer to $250. And it's all from memory so it could be +/- a few bucks.
Looking back, I guess if you're replacing everything except the frame I can see how it can get upwards of $500 easily.
