If you end up having to junk this frame I will buy it off you for $50 and shipping if it is around 60cm in size.
Obviously, if you can get a replacement or some deal by turning the frame in I would do that, but if you are faced with throwing the frame away I would take it and fix it for myself.
Also, you may be able to send the frame to Calfee and have them fix it. The price from Calfee fixed and repainted in the area of the crack is usually about $400. If you do go that route, make sure to check the entire bike over to verify that is the only problem.
Carbon frames really are not that hard to fix, I posted how to do it on the 'Would you ride this frame' thread. You could easily do it yourself and have it be strong with only 2 oz of weight gain. The question is whether or not you want to tackle a project like this. If you fix it correctly it WILL be stronger then it was initially (so long as you are covering the broken area, using enough material, and there are not other areas that are broken), but regardless some people will forever be worried.
