This past Thursday, 2011 Jan 13, I debated the Calvinist apologist Jamin Hubner, who according to his web page is the professor of theology at Jesus Bible Institute in Rapid City, SD, on the existence of God. You can listen to that debate online here , and read a transcript here . The debate was held over Skype, with moderator Joshua Whipps. Jamin is involved with Prof. James White's Alpha and Omega Ministries , though I do not know in what capacity (except that he blogs on their website). He's a presuppositionalist apologist, and has authored/edited at least three books on that subject in the past few years.
