I had one of the cheapy flourescent orange garbage bag sausages, I just replaced it with a Dive Rite reusable marker. I just had to try it out and it only took one big breath to fill it. It also has an interesting mouth piece Im not sure if I like, it has a "jamb nut" that prevents you from pushing on the mouth piece wich is necessary to inflate it. Im thinking this is to keep the inside of the tube dry, but I would worry in a stressfull emrgency you may have a problem unscrewing it, pushing in this, blowing on that...
