Well, Tibbe, after looking at your gallery, I see why most of your images take 20min max to render. Most of my images render in under 20 as well. But keep in mind that when you a) have multiple light sources, b) have raytrace reflective surfaces and c) have reflective/refractive surfaces, render time goes up exponentially. Add to this the complexity of the object (# polys, etc.) and there can be a large render time. KingHeroical has @20 light sources in his render, and it looks like the glass is refractive. If he is using Bryce, I'm a little impressed it took only an hour...
