Evidence of a poor auction in one tld is not evidence that another will fair better. Although I do agree that there are some shocking auctions at sedo.
My main point is that to me I would not be happy putting my domains into an auction where the only winner would be sedo.
From the .pro auctions on sedo I have viewed, there is not one I have seen that has had more than 1 bid. Perhaps business.pro will be an exception.
