The difference between a ceramic kiln and an annealer is a ceramic kiln is designed to ramp up to a high temp, then ramp back down; an annealer is designed to ramp up to a certain temp (between 900F and 1100F depending on the type of glass used) and hold at that temp, with the possibility of holding again at a lower temp (usually around 700F). With beads, and thin fused pieces, the second soak is not that important due to the relative thinness of the glass. If the kiln you are looking at will do that, plus go up to higher temps for PMC or fusing you have a multi-use kiln. You don't need to be fusing in any kiln that you can't anneal in. Fused pieces need to be annealed as much as lampworked pieces for the exact same reason. The amount of annealing required is based on the thickness of the glass, not the techniques used to heat the glass. For more info on annealing, go to Henry Halem's site
