The price of it brand new was $1149, so the frame fork used should be about $400-ish, give or take depending on quality.
I have an '05 Tourmalet and LOVE the darn thing. You can put 28C tires on it for a comfy all day ride, or you can strip it down and race it very competitively.
If it fits you, I'd highly recommend it. But then again, I'm a little biased, being that I really really like mine.
nobody will pay 400 for a used alu frame w/ bontrager fork... try 1/2 that
