I was just given the Medtronic Minimed over 2 years ago. In this time I have been totally satisfied with the pump. Once real consideration for me, and still would be, is the ease of filling the cannula and the whole 'set change' thing as I think the pump screens etc would be something most people could pick up (the Medtronic pump is very easy and all that needs changing regularly on it are the basal rates and holiday/annual hour changes. The other settings were all set-up with DSN , but the manual is very clear too if you needed to go back to anything e.g. to change the insulin sensitivity time).
Going back to the set change, once I had got used to the method, I have not had a single day's problem with cannula blockages, kinking, no delivery alerts or bubbles in the reservoir. In 2 years I think that this is excellent and it gives me a lot of reassurance in my little pump. I use the Silouhette sets with the pump but it's what sets suits the individual the best as you'll find out.
