You've probably made your mind up by now but I thought I'd give you my feedback on the Vibe anyway. I've had mine for about 5 months now and I do like it. However it's my first pump so I've got nothing to compare it with. I find the pump itself very easy to use and so far it's been reliable with no mishaps (I hope I haven't tempted fate there), but from what I've read the features it has are pretty much the same on all pumps.
Any negatives are minor, for example I can't hear the reminders (to test BG) especially if I'm out in company and too busy talking. However I remember to test without any prompts so its not an issue for me.
I like the Diasend software that comes with it, it's quick and easy to use. Other than that, it does what it's supposed to do.
I've had a few problems with the Inset II cannulas that come with it but that could just be me. Anyway, good luck with your choice!
