Question about routers - fixed base or plunge?

Question

What is the main difference between the two? I'm guessing the plunge is more diverse simply because of the price, but what makes the two so different?

Answer 1

a plunge router allows you to make multi depth cuts quickly and allows you to do plunge cuts (mortice's for locks etc) on the move without having to stop. whereas a fixed base router would normally be set up and used for repetitive cutting at a predetermined depth.
