One quick note, if you ever do get Modelsim-DE

Buy floating license, but make sure to get more waveform viewer licenses than simulator licenses (3 guys can use one simulator license most of the time)

(They don't advertise this, but will do it.) To start Modelsim without globbing a simulator license, you need to start it with vsim -lic_no_lnl option

Most of the time you are looking at waveforms. use the waveform license to do this, and run your actual simulations in batch mode. If you simulate from graphics mode, you hold the simulation license the entire time you have modelsim open.
