The only one without tubing, so far as I know, is the Omnipod. They will happily send you a fake pod for you to wear and see how you like it. In my case, I tried one on the back of my arm, and it was so hard to remove, it left a big bruise. :-( Then I tried another one on my hip, and it interfered with de-clothing and re-clothing when I went to the bathroom. And I personally, don't want a big lump on my belly or my leg, so the Omnipod is out for me. I do know that they are planning to come out with a smaller pod.
The other problem with the pod is that you can't tell if the cannula has come out, since the pod itself covers the insertion site. Of course, rising BGs will tell you, but what if you're out of the house and forgot to carry a spare, plus spare insulin?
So, for the above reasons, I have decided, for the time being, to just hang on to my old pump (which is now out of warranty), because new pumps and new features are coming. I'm waiting for a pump to be integrated with the Dexcom, which I really like, but which is annoying, because you have to program the pump AND the CGM. I'm perfectly happy with a tubed pump, because I always keep it in a pocket, and the tubing is always tucked in, so no problem. Also no problem sleeping -- it migrates wherever it wants to, and even when it has fallen off the side of the bed, the set hasn't pulled out. On the rare occasion when I wear a dress, it's tucked in the side of my bra, or on my undies, or in a leg pouch. I don't particularly like those places, but the tubing is not the problem. It's the lack of ability to get to the pump discreetly.
But, anyway, I concur with Timothy -- contact all the pump companies, and see if you can get loaners, because it's too big an investment to find out you're mistaken on!
