I just wanted to add that all of the major pump companies will send you free information kits and videos on their pumps if you ask. Some will even let you try a "loaner" pump for a few days (with saline inside not insulin!) to get a feel for it.

Since it's a big investment, don't be scared to explore.

Common pumps:

MiniMed
Animas
Smiths Medical Cozmo Pump
D-Tron

There are also 2 less common brands I think, but names elude me. Amigo? I think that's one!
