My ROM/FX kit is ordered! It is a sound system that will make my voice sound like a real trooper. I ordered the classic kit, which includes a static burst voice amplifier, a microphone, a speaker (I think I will buy some others), battery and a PCB balloon (whatever that is). Oh, and of course an instruction sheet.
Check it out here, there are some nice sound samples under "Photos and sound". :)
The thing I'm curious about, is how my female voice will sound with this kit, I hope I can tune my voice down. ;)
