Like "You really need to look at their websites and see what each one can do. I put the Ping at the top of my list because you can control it from the pump meter or the pump itself and uses OneTouch strips. Some people want tubeless so that leaves the Omnipod. Some want features in the Minimed and some like the Spirit (which has wireless capability pending which should make it a much better system). myomnipod.com animas.com accu-chekinsulinpumps.com minimed.com"
