I am glad that you refered to it as a tool because thats all they are. I would still be on MDI myself if it was not for my basal requirements needing to change so much throughout the day. It is definetly a personal choice and is not for everyone.I'm an MDIer and don't see any reason to change since I'm well controlled on my current regimen. I think no matter what the delivery system, it takes committment and effort. I just don't see the need to incur the additional expense right now. Who knows...maybe I'll feel differently in the future. I know that many, many pumpers are very happy with their tool of choice.
