I use the one touch ultra easy. It was the one I was given by the hospital when I was diagnosed and I've just carried on with it.
I find it pretty easy to use, though you do still have to insert strips and lancets. I think they have changed the design on the finger pricker recently as when I got a spare a couple of months ago it was a different colour to my original one and it much less painful to use. It's fairly small to carry round too.
The downside is that it does not have any extra features, there is no way to store your insulin dose on it or look at graphs of your previous test results. You can download hte results to your computer but it would be handy to have it on the meter.
