I start seeds in either straight vermiculite, or sometimes with pro mix in the bottom and vermiculite on top with the seeds. The great thing about vermiculite is that it will not crust over on top like peat-based pro mix, which makes a crust when dried out that sprouts cannot penetrate.

I buy my vermiculite at Menard's. It is sold as insulation, but the label says "product of Sun Gro horticultural company."
