Pick up the third burner. If you are going to do a herms or rims system, heating your strike water and your HLT at the same time will make things go much faster and smoother. I occasionally set up my rims system for step mashes and will keep the HLT a few degrees warmer than the mash. The extra burner makes setting it all up much easier without having to wait for the HLT to cool back down after heating strike water.
