I’m also researching pumps at this time. I went to an expo at my diabetes clinic and all the companies were there. They all pretty much do the same things, the major difference I saw was the screen. My eyes are pretty good, but I found Medtronic the hardest to see, followed by Cozmo. Animas was the best screen, bright and in colour.
They all pretty much have the same functions, just called by different names. Another think I like was that Cozmo and Animas had a luer lock system which meant I can use the infusion set from Cozmo if I wore an Animas pump. Which is good if you find that the infusion sets from your pump maker do not work for you.
I really like the Omni Pod only because it is tubeless. The only thing is that it is big and I have read people have a lot of problems with it. It is not available in Canada though, but the Medtronic girl said they are working on one along with the other companies.
Medtronic has the CGMS, but it is not accurate and it is another separate site and set. I was told by Animas that they are working on a CGMS that will be all in one with the infusion set.
I say call up the companies and get the reps to come to your house, play with the pumps and see what you like best and what works for you. Check out the Pumpers Forum, there a lot of discussions there comparing pumps and giving info on different pumps.
