Hey Ruby:
I thought that you were doing Good on the Byetta? Pumps are only for Insulin.
My Endo made an appointment for me with the Pump Educator. I was showed all the pumps at my appointment with the Pump Educator. She explained all of them and let me and my Hubby play with them and we asked all our questions. (Yes, I dragged my Hubby with me since he's the Techno saavy one). We both agreed on the Animas 2020(tubing), if I wanted one. Since the Omnipod(no tubing) isn't approved in Canada yet. People do have problems with the sensors sometimes. They still like it though since they do not have the tubing getting caught on things. The Ping(no tubing) isn't approved here yet either. Many like the MiniMed Paradigm(has the tubing) also but it is up to the Person who uses it. There is also the Acu-chek Spirit(tubing). Not many use it but the ones that do seem Happy with it.
Some People go from one pump to another if they are not Happy with the one they are using and if their Insurance allows them to. If you don't get a lemon pump or supplies, and tech is easy to you or your SO, then any could work for you(if you don't get a lemon). Some People just get fed up with pumps because they can't get their sugars down or hate being attached to a pump 24/7, so they go back to multiple daily injections(MDI).
Pumping Insulin is a Good book to read, whether you pump or not.
