There is one non-Calvinist that was involved in the Building Bridges conference that I have gained a lot of respect for.
His name is Danny Akin, unlike many other non-Calvinists he seems to have a high regard for Calvinists. He also has defended Calvinists for their high regard of Scripture on more than one occasion.
Something tells me, that he is going to take it on the chin by his fellow non-Calvinists, though I have yet to see this happen.
